excellent style man. Yeah, it would look great on any dark color and maybe some light ones if you got the color scheme right. My only suggestion would be to grunge it up a bit. If i saw this brand new without a scratch on it I wouldnt buy it. But if i saw it at a thrift store and it was scuffed and worn in than it would be a total instant buy. I'd say apply some grunge-brushes to it in photoshop.
i like it .. it reminds me of those black felt/marker paintings .. the square/boxed in shape bothers me a little ... being that on a tee it would be a box on the front..maybe re-work the outline into a more organic shape?
any and all comments and suggestions welcomed
