I am setting a monthly goal of $200, saving it for child support so I dont have wages garnished or policemen knocking on my door saying "where's the money for your kid??!?"

Commissions are going to be in tiers, and always accepting donations:
$5 - sketch
$10 - colored sketch / lineart
$20 - full color art
---
+$5 - per additional character
+$5-10 - for background**

** based on complexity/difficulty, I dont normally add backgrounds beyond props
