Yep, I removed it from the challenge because of the transparency. But if you fix it in time, notify me by sending a message and I'll try to get it back in!

Looking good! :)
Remember, no transparency for the Weekly Challenge: I would replace it with a colour from the challenge's palette.

Hey, welcome to PJ! This is a pretty good caricature of Lincoln. There is room for improvement, though, when it comes to the shading - the darker shades of color here cling to the outlines of the piece (this is called "pillowshading"), which makes the whole thing look rather flat. Lincoln's hat, for instance, is mostly a cylinder, and should probably be shaded like one.
