? for all the artists out there...

I am not an artist but I do love to do art work.  I think if people are already paying you more, try uping your price to a flat $100 and see what kind of reaction you get.  You can always negotiate it down a little if you decide you want to but people are not likely going to negotiate you up.  Think about how much time you put into it and the cost of supplies etc.  If I really wanted a nice ortait made for my dog I would pay $100 probably.  Your color drawings are very nice.  I don't know what the original subject looked like but it looks like you put a lot of time and detail into them.  Think of it in terms of how long it typically takes you.  Like say $100 divided by 10 hours would only be $10 per hour which doesn't sound so bad at all.  I don't know....just a thought to help you validate what you decide to charge. 
 
I love the drawings though!

I'm not a portrait artist but I am an artist (of a sort) for a living. I think your prices are too low. You are making works of art - and highly personal ones to boot. I think $100 for the 11x14 is perfectly reasonable and maybe even a little low if you are really good. How long do they take you? Do you frame them or mat them?

I am an artist and a musician, and a long-time self-employed person. The number one mistake self-employed people make is not charging enough. You should be making much more than $10/hr. Remember: you aren't going to be working 40 hours a week at that rate. But if that is a starting point for you, I would say charge $100 for any portrait 8.5 x 11 and more, say $150 for 11 x 14, then $200 for 11 x 17.

As art goes, this is very cheap. Find out how professionals package and sell their art, and follow suit. Matting should be done by a professional until you learn how do to it well, because it isn't as easy as it looks!

Even if you aren't doing this for full-time money, you have to realize that you have more costs than just your time. You have to buys supplies, pay rent, advertise (including online costs), have some money in the bank for emergencies if you get sick, etc.

If you get a booth at the county fair and do quick five minute portraits, then that's a different thing!
