I guess I tend to think of them as illustrations (since I was working from the books only) and painted them before any of the movies came out. So some details will differ. All are acrylic on gessoed paper. My aim was to portray them as if a wildlife artist like Robert Bateman was painting them.
This one is "Buckbeak" and painted in 2000-ish (after the book, Prisoner of Azkaban came out), 12"x16". My thought was for every large, charismatic creature I would paint one of the small, weirder ones.
This one is the "Golden Snidget," approximately 7"x10." Apparently they used to use a live bird in Quidditch.
This is the "Thestral," approximately 9"x12." Painted after the Order of the Phoenix book came out. So it's a bit more horse-like than the movie shows it.
This is the "Ashwinder," approximately 8 1/2"x11." Never leave your magical fire unattended.
For some reason I couldn't seem to get a decent photo of the piece, it looks better in reality. Might have something to do with the paper having more texture than the others and the fact I was using some glazes to get an ashy, hazy look the the embers.
