After buttloads of delay, I've decided to test the waters and try commissions.
We'll start like this:

Opening three slots

Lineart
Head and shoulders: $5
Full body: $8
Lined/anime-ish style, color - Example, Example
Head and shoulders: $10
Full body: $15
Painterly, color - Example, Example
Head and shoulders: $15
Full body: $20

+50% for additional character
+$2 for simple/monochrome background - Example, Example, Example (I will count vector designs as simple)
+$5 for full color background - Example, Example (Yes this is technically monochrome, but it's more complex)
Default is solid color/gradient
All works are digital

Note that for lineless/painterly I highly recommend against asking me to do human characters. If you insist, I will do my best, but I don't want it to be a waste of money.
Also, if you ask for anything mecha it will likely take significantly longer; I may charge extra depending on the complexity.

If there's enough interest I'll post more minor details. If you are interested, reserve a spot with a comment here and I'll get back to you with a note.
