CAN you live with it?! I don't really think you can. I still think it's a fine piece of work, especially since you completed it, which is waaaay more than I can say about my own mosaic attempt. But wasn't that one eye just awesome?! ;) ~mittns
If you compromised the "bricks only" policy, you could add the odd detail around the gun with plates (trigger guard and sight at the front, would suffice), to make it more recognizable as such. But hey, great mosaic!
