Transformation Realization

He couldn't believe his eyes, what was happening to him. The searing pain made him quiver, it felt hell just trying to breathe. He clenched his chest in immense pain, his ribs responded by pushing themselves out one by one. His gums hurt as incoming sharp teeth were literally tearing them apart. Blood fell from his mouth, he was beginning to lose his balance. He reached out grabbing the closest thing he could to prevent himself from falling down. His hand landed on the mirror, his new found claws digging into it. His spine cracked loudly which caused him to yell, he shut his eyes tight as it continued to change. It rose from his back and made itself visible beneath the skin. He could only open one eye, but with that one eye he saw a horrific image that stared back at him.
What was he becoming?

Just a concept for one of the chapters for my Graphic Novel in the making, HOWL.
I doubt I'll actually use this scene in the Comic, (Not nearly horrific enough for the 1st transformation) but I'll probably use it on another character in other stories somewhere down the road.
