I was originally going to present this with all the colours done but the lines took forever so I want to show this now. I will upload a coloured version when I'm done.

This skin concept started when I was thinking about how Mercy's staff could make a good scythe. I was initially going to go with the raven theme but I decided against it because Reaper already has a skin like that. So I chose another animal that often represents death, and an animal far more appropriate for Mercy, the moth.

You can see the moth elements in the shape of her head piece, her tattered clothes, and some of the smaller designs which I tried to make similar to a moth's shape. I was going to make the panels in her wings spikey but I figured that would look too much like her Witch skin so instead, I went for a broad, rounded look like a moth's wing.

Another strong influence was Bloodborne. This should be obvious to anyone who's seen that game. The shape of her hood, head piece and collar is very much drawn from it. The bracelets around her arm were inspired by Mergo's wet nurse, and the scythe was inspired by the burial blade. u/slasher-flicks requested a version of Mercy's staff that was based on Bloodborne's rifle spear, and I really liked that idea so I included it.

Lastly, one of the first ideas I had for this skin was an open back but I was wondering how I could then attach her wings. That's when I came up with idea of a jumble of tubes that connect her body to her wings. Imagine the tubes are all red, because that's what I'm planning to colour them. It's suggestive of blood but technically isn't.

I'm planning to give her milky white skin, brown/black clothing, and small hints of silver, red and gold. But if you have a better idea for a colour scheme, please let me know!

I hope you like it.
