This is is mainly a support and information forum for Artists of all abilities. You could check out the Business and Legal Forum to find out where it would be best to sell your work.
And of course feel free to post your own work, once you have two posts in the appropriate forum and have some conversations with fellow artists.
You might want to read the User Agreement and FAQ's thread pinned at the top of this forum or follow the links in the signatures of mod, guides and admins.
