It does sort of give off an unfinished look. The center is cool and all, but I'm not really big on cutouts or stocks in signatures. Mostly because if you use a stock or cutout, that's a chunk of work that isn't yours. Yeah you can doodle all over it and make it look pretty, but that doesn't make it any more yours :P. That being said, I can't tell where you took the time to do something original with it. I like the grid designs, but the stock overwhelms it. I'd like to see more work in it, but if you're going for minimalism, that's entirely your call. I would be interested in seeing what else you could do with it though.
