I think it would be cool if we could make statues of our Characters or even friends on our Sprite Islands.
If you couldnt put it on the island, it would be a great idea to at least make one in the model room. That way everyone could at least start out with 1 free model of themself(just like ur islands starting sprite), and if you could make models of other people it would even give people a reason to view your statue room.
And imagine if you could make a larger number of them. A chance to show off all the costumes you have in your archive by making models would give people a reason to to collect more.
Now take that thought on different character models...and add mounts ^_^
just imagine going into your model room... "and this is me in [such&such] vanty, riding [thingamabob] mount, next to my friend wearing [this&that] vanty riding their fav [whatchamahcallit]"
Everyone starts with a free model.
Different Costumes would make models created more unique.
A chance to have models of your friends would give them reasons to visit your island.
Show off your costumes/mounts.
Less room for creature models.
Price of costumes might go up alittle.
People become jelly over the costumes you have.
