Superfast Catwoman sketch

I haven't posted anything in ages, mostly because my work is all sketches and scribbles. I decided to give myself 20 minutes to do a pose sketch starting with two blocks and then adding in refinements. It was just a female figure and then I turned her into Catwoman on a whim. I hadn't closed PhotoShop down when I went out so here it was when I came back. It's rough as hell but not the worst thing I've ever drawn so I decided to add a reeeally simply background and post it up. Maybe I should post more sketches like this as I usually just discard them.
