Hey, this is alright!
Now, I do prefer that you have color in your submissions, but this was still not bad. The good thing is that you manage to show different versions of this character. Most of the versions are similar but the two in the lower right hand corner are more abstract. I think it's interesting how they stand out, given their position. The best is when he's slowly shapeshifting because that has the most unique design. It seems like this character might be similar to the Slenderman.
The claws seem to be different in this one in that there are only a few on each hand. In one part, it seems more like he's holding something rather than a part of his body being shown. At least you are nice enough to include brief descriptions. I am very glad to hear that you were fortunate enough to be part of a comic book company. You definitley have potential.
