I’m going to be blunt and say your outdoor lighting really sucks. The color is a bit odd (it’s a cool light, which doesn’t work too well for this setting. Try using warmer colors. Ambient is way too bright, and I’m questioning your choice of textures
For example here, the choice of textures really sucks. Not enough variance in brightness, and the rock-to-grass blend lacks any detail in the textures (should be a bit darker and noiser grass) Also the tall walls really make the space feel enclosed. Add some extension into the background, but make sure you clearly define borders.
Ares feel really flat. This is part of your lack of noisy textures! Make sure to use a wide variety of textures in a gradient fashion to make areas pop out more than others. Interior lights are dim! Make them more focused and brighter (not too much, but enough to where you can see defined shadow shapes.) This also helps the flatness of things. More decals! Decals are life savers and can make bad areas look pretty nice. for example here
It’s really flat. A texture change to a noisier texture (like a cobblestone or brick tile would loook great) then some decals and junk (like bushes or a tree) would help the flatness too.
I’ll try playing to get more feedback.
