Advice: Commission Prices

[paradedemon.livejournal.com]

EDIT: Please note, I'm under the age of 18, so I can't take money commissions yet.

I've been getting people seeming to call me "greedy" or "crazy for having commissions for 400 points and more.

are people getting greedy right now and want more for less?
i think my art is really quite good so I take points commissions on DA for points all 10 $ worth or less.

yet people ask to take that and such to 100 points?
It bother me that people call me greedy for wanting a decen money for commissions? It's not even money, only virtual currency that's purchased for money but cannot be sold for money P:

I've only had people "satisfied with my prices" when I sold things for less than 40 points a year ago pretty much P:
