Wow seriously, you gotta be pretty darn high-and-mighty-ish to complain about the colors and "reject" something like this. Those warm colors are so dynamic you can almost feel the light and heat. The drawing is amazing. I like how there's a nice contrast between Wolverine and Colossus, both in terms of colors and in terms of how Colossus is standing there like an immovable statue blocking the way whereas Wolverine is like a beast lying in wait and all pumped up and ready to kill. This is going in my favorites!
I never saw the cover that actually ran, but this one looks really REALLY bad ass. The reason for rejection seems a little... retarded. Either way, at least you two got another kick ass picture out of it!
I need to say it... Wow! You've done great job drawing this picture! The colours are really great. The only thing I could be disappointed of are the face of Michael (you know, Colossus), which is extremely scary. I remember him from the comic as one of the most peaceful characters. I remember, when he cried by his brothers' body, this is one of my beloved moments.
The second thing, the lesser, is the mask of Wolvie I remember it as a bit bigger than in your pic, but it doesn't really matter, does it?
But even with my suggestions the pic is awesome! Good, very good job!
Hokay, I've always hated Emma's little shoulderless-cape-thingy-outfit, so man, it's a MEGA compliment when I say this Keith dude actually made the getup look great! And this 'color' crap can stuff itself where the sun don't shine. Seriously.
