if I want to sell my art..

Yes I think it all depends on how good the drawing is, and how long you put your time and effort into it. You can also check out art online or ebay and see what other people are getting for theirs.

I draw and sell my work you have to consider te amount of time you spent on it and the size of the drawing i mainly draw pet portraits and do not usaly sell for less than £80.00 . customers have asked if I do not want more so then i can up the price next time.

Whilst an art school training is very useful to stretch your abilities and refine your techniques, it certainly isnt the only criteria. At the end of the day art is worth only what someone will pay for it, so you need to strike a balance and experiment with pricing. Never charge less than the minimum wage per hour, so always have a rough idea of how long a piece took to make, then add in supplies, framing etc. In the early days its good to keep things reasonably priced so that plenty sells, but always tell those early buyers that it is a specialy low price. Look at similar artists and see what they charge, don't underprice yourself but don't be greedy either at first. once you have an agent you can leave pricing to them often as they will fight to get you a good price, but they also take a commission so its swings and roundabouts.

You should focus more on your skill than your education. But be realistic. Take a look at the other work out there and really evaluate yourself. This is one area that a drawing class would really help in, because you would get critiqued. There are probably placed on the Internet where you can post your work and get critiqued. Having said that, search around for art shows that are accepting submissions and enter! I would never price a drawing for less than $50. That is a low-end price but not so low that you are doing yourself a disservice. And you may even win a prize at the art show! Good luck!

I think it really depends on the topic, how good and unique it is and whose buying. I don't think you;d have to have a big name to get your stuff sold. An old friend sold some of her art off a website, sadly I forgot the site. I too am interested in selling art, but I think I need to increase my skill just a tad more ;P
