The uncredited artist who actually created the final visual design of Ms. Pac-Man was Sharon Perry/Barr, who also worked on Discs of Tron, Spy Hunter, Rampage, Demolition Derby, and many other classics.
(I got to see some design artifacts while working with her on a Sega Genesis game. You can find a mention of this, as well as a picture of her as a vampire, here: https://www.arcade-history.com/?n=the-spectre-files-deathsta...)
There are some details about a recreation of Crazy Otto (where you can see some of the game graphics) here: http://www.pacificarcades.com/crazy-otto.html
Here's a photo of the daugherboard from Ms. Pac Man (which Crazy Otto begat): http://lawnmowerman.rotheblog.com/images/msaux.jpg
