critique tablet drawing

Critique? I haven't drawn a horse in photoshop in a while. Please keep in mind that it is not completed. I will post updates as I continue to work. Any and all opinions welcome. (the different colors are going to be used as shading guides)

That's a hard angle to draw; almost dead on. YOu've done well , so far. I dont' draw on Photoshop, so it's hard for me to fully appreciate it.

Update

For someone who hasn't done it in a while it looks quite nice! I am like tinyliny though - I don't do any work on a computer. Tried once but discovered my hands preferred the feel of the pencil.

Nice job!
