That dinging thing is brilliant, sounds like something I would do (or continue to do if someone ahead of the line started it), however fortunately for me there is pretty much never a line at my bank because it's one of the small ones that no one's ever heard of. But they do have pretty cards.
Looks like you got some kind of hand after all that (or did you do the painting beforehand?), it's a very vibrant looking one.
I arrived there, it was lunch break. Half the staff is on lunch and everyone in line was on lunch. I do that every freakin' time.
As for the art, I had some of it finished, then I threw on another layer and added the hand and the black around it. I think I even screwed up on the right edge there but that's okay. It adds character.
