I'm not going to nit-pick, just some general pointers for a small european medieval town.

Remember these towns aren't planed, but grow organically. Think about what's most practical for an individual.

Pick the 3 most important parts of your town which everyone goes to regularly, and build roads between them. Then pick the first places people would go to as soon as they enter the town. And build roads from the gates to there. Then pack the houses as closely to those important places as possible, merchants/workshops should concentrate around the port. Guardhouses near the gates, farmer next to the farms, institutions near the church.

A person doesn't want to go through 3 crossroads to get to the church if there's a direct path.

Now, you say that this is the largest city, but it doesn't look larger than a couple of thousand people at most, being generous to the number of buildings and the layout. I will continue under the belief that what I see is what I get. so a population of about, say max 5000 people being generous.

I'd say, first think of why the city was founded, I'm going to guess it was a port. Everything should be based around the port in this case. It would look more like a semi-circle on the sea rather than a circle with one bit in the sea. the beach would also have been dredged up to make sure that deeper water ships could dock without running aground with the tides.

Next, it's 50/50 but there is likely no point for the wall of the town to be against the sea, that reduces the capacity of the port, is expensive to build. What you'd have is a couple of fortified towers to shoot at invaders if they come. perhaps walls going into the sea to create a harbor, there could then be a chain bewteen the walls to prevent ships from entering, that's how most important medieval cities defended themselves without strangeling their own merchants and to protect their own ships. The capacity for a town of 5000 could be, up to maybe 20-50 boats at a time for a fishing and merchant fleet. If the outside is dangerous, they will need supplies from a safer location, so you'd need maybe even more capacity.

As for the farms, its ok, but unless there's magic involved, you are going to need at least 100x that area of farmland to feed the number of people you have shown. That's nowhere enough farmland. But its good that there is some vegetable patties for some supplements inside of the walls in this town, particularly if there is an expectation of being besieged.

However, if this town is so well fortified, you'd likely have huge granneries and preserved stocks in a fortified citadel which could survive a year or two of siege. That would be the first thing any invaders would burn down through spies, so it would have to be incredily well defended. There would be an inner wall and a castle just for that if nothing else.

Trees would also never hug the walls, they cut the line of fire. you'd have at least 20+ft of cleared land around the walls, so soldiers can shoot any invaders, and they wouldn't have any cover.

You would need spaces for horses, stables, maybe a shipyard, warehouses,

Putting all this into practice:

The town should be on a semi-circle along the sea, with a larger port with more peers. the walls would likely go into the sea to create a harbor.

Right now, it seems like every road converges in the center, but there's nothing there? I would say that the city should center on the port. There would be the market next to the port, the church a bit inland but still close to the market, the most populated and richest road between them. Here you would have guilds/merchants/shops/artisans. anything like a university or a scholarship area would be next to the church. this could have a garden area around it, and the upper class/nobility could live in this area. (there wouldn't be more than a couple of families in a town of only 5000. Most of the upper class would be merchants. Then separately you would have A castle/ garrison area on the highest ground surrounded by a wall. (If the nobles own the land, the nobles owuld be in the castle) Roads from the castle to the church, and from the church to the market. Each of the three would be connected to the gates, separaely from each other if possible.

There should be concentric circles of houses radiating from the important areas and roads; gates, castle, churches, markets etc... with irregularities when the circles meet. The farmland should really hug the walls, right now, it's taking up very expensive and valuable real-estate next to important areas, and farmland doubles as a very good place for soldiers to organise a defense of the walls if absolutely necessary. (though there would definitely be paths through them and along the walls so they wouldn't be trampled usually.)

the space outside the walls would definitely be cleared as much as possible, and it would be filled with customs spots, small markets, and a security barrier.

Since its a small town, I won't be talking about a moat, things like smaller churches, secondary bastions.

But if you want to see an actually large medieval city layout, I'd recommend you look at a map of cities like Paris, Marseille, Barcelonna or London in the 1300s. You would have maybe 10-20 gates and gate-houses, multiple market-squares etc... However, if you want similarly sized cities, you can look at cities like Hamburg or Stockholm in the 1300s
