I like the rocks. Their colors and formation, the way you transitioned them at the top there. The trees are a little oversaturated with the yellowishness in the hilights... and the character seems overly miniaturized... like a midget... relative to the scale and feel of the setting. Overall very good though. 
Those trees are hawt. The transition of colour from shore->purple->blue looks a little harsh to me though.
may I suggest some dropshades that go along with your lightsource.. :)
looks nice btw
go you good thing!
I like the pine trees, everything is so nice though that the water feels out of place(maybe ripples or something.)
Looks great. Only thing I think looks a bit off is where the trees meet the ground, the shadow doesn't match the rest of the tree and it makes it look as though the trees aren't attached to the ground.
looks nice, but is the rock meant to distinguish the lower and upper floor?
Don't think it does that well ]:
Everything else is awesome :D
I love this like you have no idea...colors are great and design is perfect.....it all looks so delicious
