i'll be honest - selling art is hard. your better working. something steady. you should earn the money to pay the $30 and upload more things. but it could take a while before you get any sales. you'll be advertising all the time, and maybe not getting anything for it.
your images are very small - too small. set the camera to the highest rez. add descriptions and keywords. and fix up the horizons. only post work you would buy yourself if you had the money.
art is stressful. i work 7 days a week, 15 hour days. i see the sun now and then, but if you think selling art is easy - its not. first you have to perfect your skills, then sell things. or you can open up a ton of free accounts. i would remove the walmart stuff on the bio. its a bit depressing. if you work at a burger place, they may let you take home food....
the main perk is - more space, a little perk in extras like frames, and your own website
