To be honest, I feel like half of the genres could suit mine in some way.
My comic is slightly Game of Thrones-inspired but much more light-hearted because there aren't people dying 24/7 and good stuff happens as does bad stuff (so slice-of-life-y? but in an epic saga way), and it doesn't really have magic/fairy-tale creatures in it so Fantasy doesn't quite fit even though it's a fantasy world. It has romantic subplots, fighting will happen sometimes (action - but only every now and then), and in the end I chose Drama because of the big plot arc with a little Mystery/kind of detective story
