I clicked the link and saw nothing but ass.
Then I looked up at the rest of the body.
Upon returning to the ass, I found that it's flat as a board.
See, everything else was the schitt. The shading. Everything above the waist. Once you start dealing with ass, though - we enter a whole new level of critique.
--or was it your intention to have a board-like ass? Ya never knooooow!
...and this is a commission! Dayum! The cash flows inward, I see.
