As an artist and a true fan of the Street Fighter series I think your art is really awesome. The idea you had is absolutely cool and I strongly approve this message. Giving out unique stuff to people makes them feel special, which makes them feel better. You can make one's day just with one word and in your case you do it with an awesome sketch. I also think it's really smart because that would make people treat your business cards like a precious item and probably never lose them. Good job, Sir!
