You did a good job on these considering the material you had to work with. Again it shows that less is more, your version has less colors than the original, but this makes it more readable. I would have kept the close-up framing though since there is nothing in the background to work with. The full body image is a bit weird because of the poses. Her pose is strange in the sense that she looks so off-balance.
Ken's art is just bizarre, there is just so much a colorist can do. I'm afraid to say that despite your best efforts, you ended up polishing a turd.
