Mommy-sanさんのイラストまとめ

And on the cover of Wild and Horned Hermit, her haircolor changed once more, this time almost taking a blonde tone as opposed to the silver/blue-ish color in other artworks.

This is Sakuya's artwork from 10.5. Her hairdo is much more messy, and her clothes changed slightly. Her breasts are also bigger, leading to the "pad" meme.
Her face, by comparison, has become less round and more pointy.

Her hair is also slightly darker.

Look at Sakuya. This is the first official artwork from Touhou 6. The hair looks light silver, with a hint of pink. The top is shaped outwards.

Just compare the line thickness of the left one to the right one.

One has clear outlines, one very thin lines all over the place. This makes it very difficult to parse visually. The fact that the background pops as much as the foreground doesn't help either.
