Drawing failure; Design Success?

So I'm working on a robot design for character design class.  Drawing isn't exactly my forte but I like to think I can put together some decent layout drawings.... which is what these are.

I'm liking his big beefy legs a lot.  I should probably spend less time on them really.

I'm working on proxy modeling it right now so that I can actually draw it up and give it lots of added detail for the final model.

I'll be posting some of that later.
