Im in the same boat. I myself love DA. Much like any other community of the arts, its just about networking. I've met some cool people on there and done some lil things here n' there for some just so they know Im around and alive

You gotta just keep doing what you do, but do it more and more and more and more etc etc etc.... A while ago, I wanted to get back into art stuff and I wasnt getting any 'exposure' so I joined DA too. I'm getting some love, but not much, mainly because I'm not 'there' yet like some are out there on that site. You gotta go your own pace, eventually it'll come around. Also, those DA Groups have helped a lot. DA is one of those sites where you get what you give.
Other than DA why not try doing things for people around your world and do 'freelance/ commission' work. maybe just little projects til things pick up and get rolling yo

Dont charge much, you might have to do things just for free, but it may work. I wanna try that route too, but first I still need to fine focus my style a bit

One thing I would think you'd wanna do is start going to conventions and take cosplay photos there and just start that avenue going. There's so many different styles and character personalities thrown about the cons that photo taking should be a good way to get some decent work captured and posted for others to see too.
Whats ur DA account name so we can check yo skillz
