well, I like it. I've done some cartoony stuff like this, and i've experimented with all sorts of workflows. Wires would help us, as dvlenk6 mentioned. Wires reveal kinks or bad spots in geometry that can be simplified or the topography changed to make your models better and more efficient.

Here a few characters I've done, and these wires give you a bit of an idea all the drastic differences you can achieve.

I am actually supposed to build a character this week for one of our departments, so I may post it on this list when I get it done. It is not the most original idea, but it's for our cardiac rehab, so I am making a heart-guy who can be posed to do the various exercises, etc.

I love what  you have here. Nice character. Simple and cool. I'm looking forward to what you put up in the future.
