Orange: HER uses gradient. There is no usage of gradient from Mumei because she's just using basic vector arting.
Yellow: With GIMP pen tool, when you use a brush, you can't change how big your strokes are at the beginning of your pen tool line so it defaulted with being ugly clump of circle as seen on the right yellow circle, but when it bends on sharp angles on the left yellow circle, it turns out sharp. HER exclusively works with hand-drawn lineart as shown in her streams.
Blue: The thickness of Mumei lineart are even and thick, while you can see HER uses hand-drawn lineart that has the sketchy, scratchy, and uneven opacity look to it.
Magenta: Again, HER always blended her ends of eyebrows with blending layer "dodge mode", and the visible eyelids to appear more emotionally strong compared to Mumei's.
Green: HER has always used some scratchy, moe blush, on top of the fading pink brush if you inspect them closely. Mumei simply just used a circle, Radial shape, pink to transparency blush on her drawing. I even speculate she does all her drawing with a mouse.
Red: If you're not fucking blind, HER basically colors the black on top of the already drawn grey lines instead of a pen tool.
Again, mismatch color palette choices.
