not my comics, but i've been really enjoying:
XII:Of Magic and Muses, which is about a magical girl outbreak in an all girl's school. I caught fully up on its website, but the tapas copy is brand new with only 4 subscriber and 13 episodes so far, while the site has 100s of pages.
I also enjoy Kate Blast, a magical girl comic about an ex-astronaut. which currently has 18 subscribers and deserves much more. Tapas is only a few pages behind where it is on the site, at 17 episodes.
