Hello Everyone,
My Name is Andrew Robertson, I am an environmental designer in the sports events management industry, so a lot of my work is architectural and industrial in nature. I have.t had much practice doing organic shapes, but if i can do something even half as good as your all your entries, i'll be pretty chuffed.
My character is called the LEGO Eater, and he is the reason lego always has bite marks. He's a pretty fierce character, but his small size renders him mostly harmless, in fact these little critters are often crushed and sometimes swallowed accidently by children playing with there lego.
I'm going to model him in 3dsMAx, and Mudbox. I see all of you use zbrush (which i must say is the hardes program i've ever used. but thats just me). so i hope i can reach similar results whith what i'm used to.
so without further a do, here is my rough sketch:
I love lego! Great idea! This is a cool character and a lego is a great idea for the base. 
Good luck with the competition.
here is some more sketches before i start modelling..
