I think the bigger placement would be better so that it would be obvious that they were offering icecream (which I love), but it seems to fit a little better smaller. Maybe somewhere between the two placement sizes?
Also, the dragon's body is really wonderful, but I'd like a more realistic anatomically based head for it. Just a little pickiness on my part, maybe, but I think the design would be greatly improved for it.
