This is another cross-company pairing, with Wolverine belonging to Marvel & Wonder Woman owned by DC Comics.
I've drawn Wolverine before and every time I struggle with his mask. Maybe one day I'll figure it out. My wife and I originally had the dark gray on his costume colored blue, but we couldn't get it to look right. I haven't drawn Wonder Woman very many times, but she turned out okay. I have her wearing her New 52 costume, which I like. The darker red along with the silver looks iconic to me. All in all, I really enjoyed drawing both of these characters
