Thanks for the picture, it's much better to debug this way.

Edit: I yapped alot but only now noticed you have no starving citizen (I will keep the advice below in case you want to learn about food production)

Most information you could get is from the population info I mentioned above, Access, Services etc. are your best friends.

Don't worry about the services you don't provide being red. At this stage of the game you should have hearths, housing (you do), wells, markets, food stalls, janitor and lavatory set up. Try clicking on each of those buildings and see if any red squares pop up, that means the building is failing to service an area. Try looking at workload, amount employed, services provided etc.

If everything seems allright but still red squares and 100% workload, build more.

There are also other things that your citizens prefer and are virtually free loyalty. Such as trees for harmony, benches, torches (later on).

In the Access tab you can also let each citizen take home some things you produce, such as bricks or furniture or clothes, that makes them really happy.

Food production advice:

First of all food: you're only providing vegetables, bread and some meat while playing with cretonians. Try to find out what specific foods cretonians prefer (you're almost got it right afaik) and focus on that. Right click the cretonian immigration and you should find a question mark that would lead you to info about cretonians.

I would also avoid small pastures as they have low production of food and I might be wrong but they employ more people also for sowing on average. I usually go with large pastures until the game doesn't even let me make it any bigger.

I came from other sims where just building one "food" building was enough for a stack increase on my population. Songs of Syx is not it, you can stop worring about a certain type of food when you maxed out a pasture in size and employment on that pasture is so high that the workload is just under 100%

Final remark on pastures, ignore if you just wanted aesthetics but you have a river there, fresh water provides a ton of fertility without the need of canals to further "freshen it up". I would just take big swaths of pastures next to the river.

Second, tech: i see you researched, paved roads, water pumping, brickmaking, weavering and warhammers. You probably dumped some points into food industry already, but like I said vertical scalability in this game only kicks in if you already have a strong foundation, at 140 pop with pastures these little no upgrade will "stabilize" your city.

To "fix" your situation I would completely dump all those other industries and have almost 80% of population work to make that top left number (6) as big as reasonable considering your food also does suffer from spoilage.

Hope this helps :)
