I don’t think extra details would ruin anything here! Possibly post the final if/when you do make some changes? 👀

My only critique as somebody with no artistic skill is the sky seems a little too empty or there's too much of one color. It's a perfectly realistic color for the sky to be on any given time of day, but I think if you experimented with more of a very subtle gradient or maybe have it set in a later time of day where one side of the sky would be off-color or slightly darker than the other, it wouldn't feel like all washed out. On the top right corner, I really like how you did the clouds though, those feel really natural like they belong there

I think some more plants could help liven it up a bit 🌱

but it already looks really good, it's very close to what I imagine housing would like in a socialist utopia - spaces designed for people and community and not cars. simple architecture with vibrant colors, love it
