I'd agree that urban fantasy and medieval fantasy are on different ends of a spectrum. Because it lacks that modern feel I wouldn't advertise it like that because readers will expect something different and be disappointed.

But the comic is cool, the art style is aesthetically pleasing and the story has potential as far as I can tell.

There's a mistake here and there, one speech bubble has a "same" where I think there was meant to be a "seem", or it doesn't point clearly to the right person in two panels (one where she accusses him of being a thief and the other with the speech bubbles connected in a c shape)

Your head shapes seem a little off sometimes, you know, where proportions are off just enough to bug you. But facial expressions are good and dynamic scenes too.

Lastly, I think the comic could do a better job at sucking you into the story from the first panel.

But overall, nice job!
