What's this picture of a smiling character with blue eyes and light hair from?

I wonder where is this image from. Does anyone know its origin?




I am aware this post is old, but people looking for this same image is going

The picture is from the cover page of [Magicians Don’t Turn
Back!](https://www.mangaupdates.com/series.html?id=92212), a Touhou doujinshi
by Saku Saku Tei.

I spent so many hours I don't even want to say how man.
