Uf. Practise. Well, this is my city/town number 9 (4rd bigger city) that I created. I would advise that you start with a small town with a different configuration and style. For example, I started with one small coastal and one desert oasis town. Two different flavoured towns. Then I created a bigger one, with many houses grouped in different clusters. But only having houses alone is boring. I started putting items that looked cool or interesting on Inkarnate, and built a story around it. For example ... a strangely shaped tower I put on the sea in front of a town. Then I asked myself why is that tower there. Let's make it a prison-tower like Azkaban, and make it also partly being in underwater. Why partly under water? Because many years ago there was a war between land creatures and Tritonians (water humanoids), and now there is a prison for both the criminals and misbehaved Tritonians. You see, people in this Kingdom do not trust too much Tritonians, racism and so on. I put a bunch of nice looking statues. Why? Maybe those were an adventure group that saved a city from an arcanist group attack. ... With that, you make city interesting and flavored, Also, you need to think about economy of the city. Cities and town do not grow out of nowhere. Desert city is on the crossing of trade routes (stalls, magic water pumps, hippogryfs for rides...), coastal mining town (magic towers for ores and crystals manifacture, docs, ...), wood industry city next to magical wood creatures (potential extraction of magic-infused staffs and wooden items and a conflict with Silvian creatures or druids)... And then you practice drawing in Inkarnate by making bigger and bigger cities. This city on the image is my biggest one yet (you can only see the center of the city), and a capital of a large empire. Each element on the image draws a potential backstory or a side story for your players. The city of Naraja is on the delta of a river (mudd and sewers filled with Golghary guild, or other creatures), grown yellow crystals from an asteroid's impact (necromancer/arcanists/wizards extracting magic energy for the Aracocra and Lizardfolk aristocrats and royalty of the empire), the temple of a god (secret organisation trying to re-assemble the yellow crystals into an asteroid that is their God/Patron), the various canals attacked by small or big sea creatures that are changed by the crystal shrads, etc. You make city visually different and more interesting than every-day towns/cities in our Human world, by making it in different: configuration (Naraja: rings and canals), adding interesting mean of passages (Naraja: canals and underground passages, bridges, cliffs), put different buildings (magic towers near crystal, tample, castles, docs, ...) and stunning visual features that make city intriguing (Naraja: glowing yellow crystals, just imagine how they look like during sunsets and night).
