Actually, if we're comparing it to existing works then it's more akin in tone to Arrow meets Supernatural in a quasi not-quite-but-almost steampunk version of the 20th century.
As for the hunters, that basically comes down to how the world at large views or thinks about the paranormal. Very much like our world, the existence of such creatures and phenomenon is questioned by the majority of the population. Many hunters, knowing the truth, must sometimes resort to lying, theft, impersonation, and the like in order to keep their lifestyle a secret. So I suppose you could label many of them as shady travellers; but I'd use the word unknown or unnoticed rather than shady - that implies someone who breaks laws or hurts people as a way of life rather than as a means to a more noble end.
