Hmm, still no comment here? Okay, I'll be the first. It just so happen that I like Mikimoto Haruhiko's illustration. He came to United States for the first time in 1991 to attend anime convention in California. I happen to be working as staff for the convention and I met him at the airport. :D
This character I do not recognize at all but definitely done by Mikimoto. You can tell by simply looking at her eyes. You did nice scan here. Thanks much.
