I can see why this would be a hard sell on Tapas. The style is very oldskool, reminds me of old Warhammer art, or pre-third edition D&D etc. It's a style that probably predates the birth of a lot of Tapas users by a good decade or two! The lurid colours are cool, very Mignola-esque.
I don't know if it'll help you find an audience, but a couple of things that could improve the comic would be:
- Watch your lines of action through your pages. They tend to read better if you don't keep switching which direction the character is moving through panels and which side of the panel they're on. The camera is jumping around a lot on the first page in particular, so it feels less like we're following the troll on a journey, and more like we're jumping all around him. It's quite jarring and disorientating.
- Avoid having characters speaking in panels with their mouths closed. There's one panel where the troll is fighting a bunch of monsters and a few of them have their mouths open, but his is closed, but the speech is supposed to be coming from him. It feels a bit odd.
