Interesting idea but... Nice idea but takes no real skill, also pretty expensive in the store. To make this a truly interesting app you should be able to kit bash your own models from the parts you've downloaded (a 'by vertex' sticking system maybe?)and perhaps a more in depth painting system, supply uv maps for example, or paint directly on to the model with a brush, and maybe even being able to play with the shader direct (transparency, texure, etc). Also more lighting options for photos. Needs more scope for user creativity.
