Dire Goblins sure are ugly.  The art itself is really nice though.  :)~

I really like your palette, but the shading is somewhat flat. Also not digging the dark outline. This is still really neat, though.

Looks good, despite the jagged and uneven outline

octoad pallete? good taste in colors. what helped octoad was the inclusion of a few warm colors to balance it out, just an idea, but you could put some warm hues in the lips or eyes and see if you like it. outline is a little jaggy and the eyes are a little uneven (the tilt being taken into account), nice work overall though, reads well at 1x
