It's been a while since I've tried to sell art on here so help is much appreciated!

Off site I usually charge $25 (for one character, without background) for a full body commission I'm not really sure of the exchange rate and if I should modify my price for the forums

And I don't offer bust commissions anywhere else, but because it makes sense to here I'm going to. I'm even more confused on what to charge for them, however.
