3D total Speed modeling challenges

So last night i did my first 3D total speed modeling challenge. basically you get 4 hrs to sculpt whatever you can that has to do with the topic. I am going to try and keep up with these and do them. It is a new topic every 2 weeks. The last one was super soldier, which is kind of a generic topic, but hey it was still fun. I wish i pushed this design more, i should have fleshed it out on paper before going onto it. I am no designer so i have alot to learn. The nest topic is "real life cartoon". I am looking forward to that. Anyways here is this one. You can see a turnaround here http://www.youtube.com/watch?v=8JC-z7WPZ2A
