The water colour doesnt fit at all. I dont know why, it seems MUCH too blue considering the dark brownish islands surronding it. Its cracked earth near the shore, where the shore is a bright blue clean colour.
And put some detail into the water, as in some doodads or something else that doesnt make the water seem too blank. Although i guess thats how its supposed to be. (But still)
Kinda nice though.
