Try out this shading type. i really like it. i think the squid isnt well, AA'ed. i like the background, and the details on the rocks. i have to say, i love to pixel rocks.
In the background, are some fishes. i think, i took to much colors. i love to do pictures with maybe 7-8 colors. but here, i took 14. i hope you enjoy it. C+C welcome.
