I know they exist, as I have images from very old auctions, but the pics are from the early 00′s and very tiny/grainy. Won’t help much here, but she’s in the center:
A half-body title artwork and some sketches from director Shingo Adachi were in his artbook, Story of Meteor. This is probably the most help:
Other than that, screencaps are your best bet for getting the rest of her from different angles.
