That is awesome cliff and water. Shit ugly rainbow not sure you intend for it to be so.
@TINC: removed outline. I get too anal about jaggy lines D:
Agreed with depth issues, thanks peoples :)
EDIT: I believe the issue is that it has a front-on perspective but you can see the top of the ice shelf. Oh well >.>
i like the rainbow, but not the outlines on the rainbow. this is a spectrum of light, what're those outlines doing there?
i hate the rainbow but everything else i really like
perspective seems kinda wacky, also the pixel tech is good but could use more form to it, the seal just looks like a flat object that's textured
all in all it's pretty good, though. i just don't like the rainbow :P
I think we all know the insparation behind this: Dewgong's aurora beam. 
I came to that realisation too 
Unfortunately, it was always the idea and I wasn't sure what else to do .__.
@Satsume, skooba: Thanks :D
Despite how central it is, the rainbow actually detracts from the rest of the piece. The rock and seal textures are lovely.
Wow!
