Island town

I really like the designs of the buildings and the overall stylization of the forms, very clever and fun to look at. The thing that I think could use some work is adding more bright, bright values, since it's on a sunny island. More lime green highlights on the background foliage and trees, and brighter, warmer tones on the buildings would help a lot. Compositionally, it feels strange having the horizon line sitting exactly on the bottom of the picture. Try showing more ground to let it breathe a little.
This reference photo shows more clearly what I mean for making it brighter and more sunny:
