Sorry for taking a while to post this one up, a lot of things came up. I will post the completed version soonish. This is on 100% cotton paper, and the sketch is in pencil.
After they came by a magical artifact they accidentally triggered a trap. This trap sent out magical energies to those nearby it. The man was the first to be attacked by these magical pulses, transforming into a hideous beast. The woman tries to run away from them but unfortunately some have gotten onto her as well and her shoulders started to transform.
