I've had my work up on sites like Instagram, Redbubble, Tumblr, Facebook and Twitter, mainly Instagram/Twitter now. I can barely get a favourite, much less a comment from anyone. I follow all the advice on how to utilize social media: compliment the work of others, follow people with similar interest, post frequently and join groups. I feel my work is pretty good, I believe I have genuine talent but generate no response. I'm invisible. I have no idea what to do to build an audience and it's starting to worry me that people just don't care.
