This is the cover-page in a somewhat short doujinshi I've stumbled across. According to the file, it's by 640km/h, but I don't know if that's a circle, the artist, or what have you. Anyone who can identify the artist would be a big help.
Note: I will be skipping a number of filler pages, with just rough sketches, artist talk, etc.
I recently stumbled upon a cache of similar kyonko and regular Haruhi doujinshi and may decide to upload more, depending on the response.
