I looked at those color bricks immediately and thought, wow there has to be some kind of cool reason behind that. Finny is already going to be a great artist I can tell. This is by far your greatest mosaic in my opinion. I can't really stress how cool I think it is that you left those color pieces in there, those few pieces add more to this mosaic than any other piece in there. There is no reason these mosaics shouldn't have 5 smiles.
Great piece. This is your best yet, and i love how you let your son help you out and leave his own touch on it. My 4 and 2 year old girls like to dump my bricks all over the floor more than they like to help with the mosaics.
Great piece. Although no sane individual would model this freehand (guessing you've pixellated a picture or used available software), it's still a very nice piece and a great accomplishment.
Also, those of you who write reviews and wonder about the colored pieces, do you even bother reading what the author says?
