The water could have used anti aliasing, and alot of it. The clouds could have been fused with the sky and should also be dithered. The sun in the picture is actually no problem. There's jut too much big clouds for that region, You don't expect those kind of clouds. Thinner and longer cumulus'es should be cool. 4, cuz I adore the character in the piece :)
WTF!? lol! the sun should be alot brighter and you should work on the shadows more.. remember that the light is comming from the sun, not from the left...
