Frankly, to start I think your color sense is much better than mine (always admire your color schemes)... and the darker purple does exactly what you wanted it to do . Just relaying my visual experience since I'm not sure how those changes to the purple would affect the overall scheme (which does look very nice). Perhaps moving the stripes to something like yellow-orange-pink-green-white (top-down) would help direct the eye up to where yellow would contrast with the color you already have for the jacket and Eden's skin tone. Not sure where else I would start without playing around with the colors!
