Drawing on experience

I'm not a very good drawer, so I use a combination of Photoshop and a simple shape-drawing program to draw the characters I see in my head. I'm in the process of planning an armature, but the general shape of the character needs to be established before I assemble the foam pieces. The one attribute I could not portray in the drawing is the character having a pronounced underbite. I want it to be almost pelican-like.

Having a basic drawing to work from really helped with the alien sculpture. Hope this one helps, too.
