Just go the fanart route for a while. It's not dirty, you don't have to do porn, you just need to get your name out there. You can even draw the things you love, no one will judge. You will not go anywhere with your OCs at the moment unless you're an actually amazing and unique artist, and let's be honest, you aren't. Fanart lets you experiment a little while still having recognizable things that will keep your name out there.
