For every extra character you add on, you pay 5 extra points. If you want entirely head-shots, you only pay 3 extra. (Do not actually press commission on this, it was just general information)
A simple drawing is either half body or 5 points for a head-shot. There is no background and no color for this.
A drawing with full color. Without a background it is 15 points, but with a background it is 20. These can be lowered by 5 each if they are head-shots.
An art piece of anything that has a complex background (i.e., a dense forest, a detailed spaceship). If there are no characters, it is 25 points.
