As for myself, I just promote like the dickens, especially on the forum. Whenever I see one of those "post your novels" threads, you know I'm right there posting away. Something which might help is to create your own little advertisement thread. You can update it every so often which will tell forum goers, hey, there's a little novel you might want to check out.
In the end, you just got to promote it. I think you even posted your series here on the forum one time and that's how I found it. The vast majority of people probably aren't going to find it through the Fresh section of the site. I myself create illustrations to give my novel a little bit more more oomph to them.
And you know what? Don't be afraid to open up and ask people for support. I've gone up and asked for subs, comments, likes etc. in exchange for the same thing. I've gotten some new readers this way and found some interesting stories to check out too.
