 Very nice! I love that tree island.

 Awsome, this style is just perfect!

cool!

The bottom right one reminds me of Journey. 

Cool stuff. I LOVE floating islands. :D

I love it.

 Please do some more of theses sharp rocks, they turn me on a little bit. (with some AA. Pleaaaase)

 Super cool ! I absolutely love that tiny red rock island, it's a few touch-ups far from awesomeness

beautiful..i wish it was AA'd though..

 The composition and use of color in these is amazing!

Bottom Left could use some contrast tho. Other than that, each one is awesome in it's own way! Keep it up!

Wow love it. Great non AA style
