Thanks you guys, Xelar, Bakker. I try to keep an eye out for any issues, sometimes they just slip by when I'm not up on my game. Let me know if there's anything specific you see! I'm never bold enough! Always striving to get there!
These skull studies are something I've been wanting to get into more because these two are the first skulls I've painted (or cared to paint) and I want to expand upon these some more. I really favor the first one and might do a larger, more intricate painting of it. Otherwise I've been kind of doing a self portrait study along side all the other work just to keep experimenting and seeing what things I can observe. A portrait of my watercolor instructor from last Summer and one of my great friends, Conrad, which I did a few days back.
Here's his sketchbook for those who haven't seen it yet - http://conceptart.org/forums/showthread.php?t=229854
