i like the picture itself but im also not a fan of the colors . I think it would look much better if you brought it a little back to natural. It kinda reminds me of old nintendo games, i bet there is a princess in there that needs to be rescued..jk
but that just my opinion..
There's some pretty strong haloing and the clouds/sky look grainy. A few adjustments can clean this right up. Also the little bit on the sides of the building that's cropped off is a bit of an eye sore.
