The Metamorphosis of Walter White

I tried to depict the character of Walter White from Breaking Bad in gradual stages, including every canonical appearance in chronological order.
The colour scheme is significant, as each phase represents the thing that colours his life. We start with dark grey, representing Grey Matter Technologies, then we move to white, representing his family life, then green, representing money, then blue for meth, then finally crimson for bloodlust.
I’m a sucker for visual character evolution and I just wanted to dedicate a piece to one of my favourite examples.
