This is my second actual drawing and shading of an anthro shark. The first didn't turn out too well, but luckily this one was at least postable. I've been fiddling with photoshop CS3 for about 4 days now, and drawing with my tablet for 2. I'm learning pretty quickly, and I'll probably move on to more anatomy soon.

I'm not an artist by trade, so any advice about shading or drawing would be extremely helpful if you notice something in the picture that could have been done a better way then it looks like I did it.

One particularly obnoxious thing I've noticed in photoshop is how hard it is to see if a pen-tool line will give a crooked line if you tell the program to trace it. Some of my tracing's aren't exactly perfect on this image due to that, but I'm sure it'll be something I'll work out with practice eventually.
