Well, looks like the Mercy & Skorpios option won quite handedly with 69% percent of the vote. I'm thinking of reusing the environment I had used for the Widowmaker animation as it has cool lighting that i'm not sure how to replicate elsewhere. I'm also not entirely sure which Mercy model I want to go with as there are quite a few different ones out there.
Regardless I rigged the Skorpios model pretty quick and put this together. There's likely still issues with it so I'll need to fix and improve the rig as I go along. I think I'll do another update once things are more finalized and I actually start animating the scene.
Thanks to everyone who voted!
