After getting feedback from people, it definitely seemed to be agreed I undercharged for multiple characters XD Nothing else changed for my prices but any commissions over 2 characters will now require an extra charge per character requested:
Sketch - $3 (240 Points)
Line Art - $6 (480 Points)
Flat Color - $9 (720 Points)
Shaded Color - $12 (960 Points)
2 Panel Comic - $20 (2000 Points)
4 Panel Comic - $30 (3000 Points)
Extra characters: $6 (480 points) per character over 2
Sorry if that's an inconvenience for anybody and thanks a bunch for those that choose to commission me!
Thanks for stopping by!
