Great work! I love the colors except the green you put on the ground, is not that I dont like its just that I think you should put a lighter color there because the wall above seems a little bit empty, like something is missing, or you can change the walls' color.. Otherwise its perfect!!
I think I know what you mean... It's the white background against those rich colors... Kinda hurts my eyes. Maybe you could try other color schemes and decide which is better.
Overall, this is really good... as always. Hope your ♥ mood continues producing these amazing artworks. I love your style.
