Giratina seems so unbelievably hard to draw, I would never try to attempt it. But you've pulled it off exceptionally...i am really diggin on the colors and the shifts from smooth to angular that I would expect of Distortion world.
When I was playing Platinum, all I kept thinking was how much the Distortion World was pretty much exactly what I pictured the city of R'lyeh to look like. Maybe Giratina was based off of Cthulhu.
Yea, I drew one too, not from behind (regrettably) but those things are the hardest part to draw (granted it's the most detailed part possible on a serpentine form) but um... the one I did he had to face forward.
but I think it's close here, I just think adding some ridges would make them look more accurate. ;D
Argg, your way with color never ceases to amaze me. I love how you used green, red-orange, and blue but they all seem to flow and fit together. Giratina also looks great too, and the lightening is a nice tough. Awesome work!
