We probably might have to first decide how many characters each of us we're gonna put in and what sort of commission we're looking for her (fullbody, color, etc.). I'm okay with tamer only, Digimon only, tamer-rookie or tamer-mega, but not tamer-rookie-mega (too expensive). I can see that we might have at least 6 people chipping in, so there could be at least 6 to 12 characters.

Couple of things to consider:
1. Pose and outfit. Some commissioners charge more for character complexity. Important especially since we're making a group picture.
2. References (if you don't have an easily translated visual reference). Might be a good idea to get them compiled asap.
