What are the best ways to market my artwork nationally?

[ThatONEdude]

I'm a graphic artist based out of atlanta, ga and I would like to learn about new ways to market my art, whether it be online or not. I have several profiles across the web solely for my art pen name "Gonzo Fresco".

Those are just few that I use the most. I have a linkdin, deviantart, society6, twitter, and a dribbble. Are there any more sites I should consider?

fineartamerica, redbubble, anything and everything have them all.
enter shows and other contests
be on display and since you want nationally then be willing to travel and odnt' go local but if you don't have the moneyf or it stay local first then branch off to national.
move to a city that supports arts.

Great work Gonzo! Recently, Guru.com announced new profiles and portfolios for freelancers to better market themselves. Take a look and take one for a test drive in a few weeks!
