Mature Themes? (Patreon)

I've always wanted to explore some more mature themes with the comic, but never really got around to it. (Aside from that one weird scene where David walks into a bunch of Goblins bathing a Hobgoblin) How do you all feel about a bit of nudity and gore? It wont be a major part of the comic. I just don't want anyone to be surprised if a mermaid nip shows up somewhere down the line.
