Hey. Who's up for some test doodles? :-)

I had the odd idea a couple days back to try drawing characters based on shape primitives (i.e. make a model of the character and then flesh it out, as opposed to my current style). So, I whipped out my tiny scratchpad, and here's the results:

Random Female #6
Bobby Boxhair (I still don't know what I was thinking with his hair)
Another of Random Female #6, this time on bigger paper.

So, what does everyone think? Somewhat not bad for a first attempt?
