I made this Lincoln portrait from scratch today, not too bad for a first attempt...: Its made up of about 570 cents.
I do definitely see a likeness, you should try again. Just a suggestion next time have us guess who it is.
Wow! Are you gonna mount it on a board or something? You should. Maybe square it off with more bright red new coins. That's really neat and creative. How did you come up with the template to lay out the mosaic, or did you just freehand it, picking the colors one at a time, all along? I always thought making mosaics would be cool. But it never dawned on me to try one with coins, even though I've seen a few.
