I haven't been sketching for quite a while and I am extremely rusty, been doing quite a bit of non-product design work. So I gather that a great way to push myself is to actually do a sketchaday challenge, so I feel pressure to improve.
Since I've had the guts to dish out criticism on other users sketches, I thought I need to man up and put my pen? where my .. mouth.. is?

Anyway, I figued if I upload a crappy thumbnail it can only get better from here on..
