What is the difference between custom figurine tiers?

Tier 1 - you receive a model holding no objects or pets. The model will also be in the standard pose.

Tier 2 - Your model can be holding objects or pets, you can also choose how you want your model to be posed.

Tier 3 - If you have a crazy idea tier 3 is the one for you. Your model can wear any clothes (however crazy you want), pose however you choose and even look inhuman!
