In my mind, they could add on a bit and color Laylee's wings, but I'd have to see it to decide. Replacing the eyes for that Yooka pattern was excellent.
I say keep the flatter look, add the gold rims from the original and it's perfect. Brighter vs darker colors depends on what their doing behind the scenes. If we can expect some grungier Clanker areas, then the darker green seems fine.
None of this is all that important to me though
