Cleaned lines on the tilted version (13).
I'm now painfully aware of the stupidity of doing this in pixels.
I'm not satisfied with the interaction of legs and snake tail in the lower left corner.
The composition looks confused there, and all those pointy things give off an aggressive feel.
I tried to remedy it in two ways: rounding the leg tips (14); and reversing some curves (15).
I think 14 is my fav, but it doesn't really address the composition issue. Is there one really?
