Such an obvious connection, amazed no one's done it before! Love the ones that have been capped, brace-faced and finally baby toothed. And the gold tooth is a really wonderful filling of the concept, tee hee...ugh.
I think I'd like it better if it resembled better an actual set of teeth. I mean, the middle ones bigger (closer), and the molars smaller (farther) and partially covered by the others.
Aside from the nitpicking, the concept comes across as it should, and the little faces and foil details are the cherry on top.
Conclusion: terrific work!
