Join online communities, chats, forums and pages, and follow blogs, which relate directly to your genre of art.
Connections made in the real world are ideal, but establishing an online presence is extremely important too. By being part of your online community, you can connect with like minded people, get tips from other artists, get inspired and learn in general!
Perhaps someone will mention the name of a gallery or agency you hadn’t heard of but which you feel suits your work? Or they can include you in a group show they are organizing, if you are in the same genre as them?
The possibilities are endless. I wouldn’t devote all your free time to this, but explore a bit the next time you sit down and surf the web mindlessly.
Deviant Art is a great resource!
