I mean I ask to some peoples but I need to resist to put all my money in all of that, so, for that I try to only ask commission when the price are 'cheap' and not because I'm someone who don't want to put money in all of that.
But if one day I wake up with full of pic' but no cash for buy important things well...
I voted any cheapish price you choose, the previous avatars Paul and I had were like, $8 each, which isn't bad. $5 commissions are usually only good if you get quite a bit of them, though with your art, I think you could get quite I few, it'd be a lot of stress though :c So if you did something like $10 per icon, I would like to try :3
10 dollars per icon would be a lot better for me and the person commissioning me because I'd not feel ripped off and hopefully they wouldn't either :3 (considering it's 10 dollars as well, instead of my usual euro prices)
