Black & White

I've been learning a bit about how to use Photoshop this week. I thought I could make this work for the Weekend Blip-Challenge theme of BLACK today but alas, I couldn't quite pull it off. I'd like to say I don't have time to tinker further because I'm working but I actually don't know how to improve it further (without cheating and using a shadow trooper instead!). I hope you all get the idea though!
