this is an odd question for myself, because i am very irregular with commissions. my skill as an artist is mediocre at best and i only slightly excell in anatomy with dynamics and foreshortening.

on the other hand, my commissions are very local, and very few because of lack of a wider target audience. but all my commissions rage between 20 and 30 dollars. for what i have done.

I put 8-10 dollars, but that's more for a stock mnger job though in my neck of the U.S is worth an hour.

Now for art, I think its a little more complex than the hourly rate. I think skill/ability/efficiency of the artist plays a huge part in it. And whether they want a hard copy or a digital copy of the work.

Okay for instance. You have a artist that has been drawing for awhile, so they can charge 5 dollars a sketch. And make maybe 100 dollars an hour. Just quick concepts that get the visual idea across. But there so good, that its real easy for them to lay somebodys idea down on paper.

Where as a less experienced artist, might charge 20 dollars for a sketch. Now its a pretty nice sketch, but it could take them a few hours, to maybe a eight to get the commissioners idea down on paper.

As long as the artist is satisfied with the money they make, and the person that's getting the commission done is happy. That's what matters in the end. From my perspective.

Also I made 20 dollars an hour when I was doing trucking. I don't really want to get back into that field..But I may end up having to. Oh, just got a sinking feeling in my chest. Shit.

I am constantly amazed at how little the artist here on DA value their own artwork. I've seen artist charging as little as three dollars for works of art that must of taken many hours to do. It is becoming impossible to make a living as an artist. Art takes years of training and as much or more skill than many other professions, yet it gets little to no respect. If you are an artist and doing works for someone, why would you charge less money for your work of art that took you years to develop the skills to do than someone charges to say "would you like fries with that?". The artist here on DA need to start getting together to come up with a reasonable pay scale or something.

lol, I don't think anyone would pay me anything to do art for them xD

The student's jobs I've had are 7-12 euro p/h though

For commissions about $30 an hour, so about $50-70 per commission piece. (for personal use)
But I only take commissions when I'm not busy with other jobs.
I've had freelance gig's where I've charged about $70 an hour.
though, I live in Sweden and there is a 60% tax here.
