So I was just trying to edit a sprite of Teruya Otori, but I wanted to try something. I put a sprite of Sora under Teruya and lowered the capacity on both layers (on Teruya's more) and this is what I got.

Also, before doing this, I noticed that their front hair and eyes looked almost the same. That's the reason why I did this. Here's a close up picture of the face.

Now I'm doing something where you do a lineart of what you see and once you finished, you take a look and see what you've got.

I'll post the results in my Art Book.
