Black Cat Wallpaper: The Sweeper

While I didn't find Black Cat a particularly riviting anime, Sven Vollfied is my favourite anime character. Sadly I've found no solo wallpapers for him. There are pictures of him, but they're either with him behind other characters, in non-appealing poses, or just as chibis. When I saw this scan I was reminded of 'The Godfather' movies and thought it would look a bit cool. It's certainly how I see Sven, anyway.

This is my first vector, which is probably why it isn't fabulous, but I've learnt a fair bit from just this experience, so maybe I can work my way into the more complex stuff like shading and what not... (I have zero art skillz) Any pointers/critique are always welcomed! :)
