thats 1 nice lookin ass

Hmm I like it. Can't beat a nice tan  .

The anti-aliasing is a nice touch as well. I'll have to practice.

better. here's an edit. just removed any banding I could find and added AA where I thought it would help. also tweaked the palette, as I felt yours was a bit washed out.

np. a description of banding and other pixelart terms is found in this comprehensive tutoial (if you haven't stumbled upon it already). the 'Ramblethread!' that I link to in the description of the tut is also muy educational.

Wow...you really know your pixels. First I've ever heard of banding. Getting my pixel art education on right this moment.  thanks.

the little back dimples just above the ass look weird. there's a bit of banding on the low center of the ass crack, and some jaggies on the bottom of the cheek on our right (as well as the shadow on the lower left). looks good otherwise.
