Out of Curiosity.... Limited Commissions? (Patreon)

A friend of mine has a Commission Tier on his Patreon, which is awesome *nods*

I might consider doing something similar. 

Limit it to around 4 Patrons per month, maybe $120 monthly tier. Maybe more.

Patrons in this tier get an animation each month (background, limit 1 to 2 characters, 4-5 seconds in length, allow more mature content)

Just a thought for now ^^

Thoughts? Takers? :)
