I know, it's fake currency on Gaia. But I base my Gaia currency intake on potential real life sales. Of course I take in the fact that my work is traditional, and a little bit of quality is lost when I scan it, but my work is definitely better than some of the CG artists I've seen here.
Gaia is a BAAD place to make a basis on how well your art will sell in real life.
1) You are a traditional artist, and probably will present and sell your art in a tangible real-life setting (and if not, I would recommend that to you, alongside an online personal website gallery). Most of the time, people are more willing to buy traditional art if they can hold it in their hands. There's something very nice about it.
2) Is your target audience high schoolers? Even though there are people past high school (and those who haven't gotten to it yet who probably are breaking the age requirement of this site) that is the bulk of the ages of the people who will be seeing your work here. The majority don't take this place seriously in the slightest, so this is a bad place to get feedback to see if your work will sell because the majority of the population doesn't care for anything except procrastinating on their homework and spamming for gold. Plus, there really is no set equation to how Gaia gold translates into... whatever currency your country uses.
I'd recommend finding a community of artists who actually have experience taking commissions and selling their work to get a feeling of how much you should price your work and then start up a small, but
real, shop. (maybe you should look into artist corners in conventions?)
3) Not all, but the majority of the audience at this site, when looking for artwork will nose straight to the anime. On here, anime is a hot commodity. In the real world of selling art... not so much. I'm just saying, if a modern-day Van Gogh started doing avatar art here he probably wouldn't get as many buyers as the shiny anime artist across the road. But, the prestigious art museums would be scrambling after his work. One man's trash is another man's treasure.
Basically what I'm saying is that the art buying audience on Gaia is so narrow minded. Most wouldn't give a flip for abstract painters and sculptors, who would otherwise be famous in the fine art world.
So Gaia = bad place to judge the successfulness of your artwork.
Unless you are targeting the anime loving /high school audience.
