Wow, this is amazing. So many great stylistic choices, and I love how reminiscent it is of Mucha. I'm not sure I agree with it being done in greyscale,,considering the immense vibrancy of the story itself, but this work really is mighty impressive.
Thanks so much. Mucha is my favorite I prototyped a number of versions in various colors but I didn't like any of them. When I threw in a nice vibrant color combination in any given place It would always make the patronus seem dead and unfinished because I couldn't color it very much and preserve his absolute glowy-ness.
