After finishing the Super Hero panel, I've gone back to the Harry Potter one. I'm going to try to keep some consistencies in these portraits, namely the silhouette behind the figure, the more angular construction of the shapes, and the deeper tones of color. Unfortunately, these photos are not showing those colors as they look in person even after fiddling with them in PS. But these will give you an idea of what I'm attempting.
I ended up putting the Sorting Hat down lower so I could show more of Harry's patronus. Also moved Hedwig on to the broom. Again, I began with a toned panel and I'm painting into glazes, trying to model the forms. This is after 2 layers of oil glazes.
