I don't know if I am biased, too attached, or already used to the original designs, but the edits don't really appeal to me.
The change to Yooka's mouth may affect his expressions a bit too much. He also looks a little too arrogant/brash/confident, or maybe even a bit sly or mischievous. Not sure if that is the personality that they want to go with.
The expression on Laylee's face is changed quite a bit as well, which again might interfere with the personality that they have in mind. Laylee is described as something like a "wise-cracking lady-bat", the edit looks a little too guano-crazy. The original looks enthusiastic, but just sane enough to be able to talk smack to others. Laylee's face also feels surprisingly empty without the large nose, but that may be me getting too used to the original design. Or it may even be the reason for the nose in the first place?
The shirt for Yooka seems fine though, the only potential problem being the difference in detail between the clothing and Yooka himself.
I do not really feel the same about Laylee's hat though, but maybe it just looks too oddly situated to me for some reason. I think a hat like that would be actually pulled over the top of someone's head rather than resting on the top of it.
Also Yooka's finger tip got chopped off, and I think the polygon count in the edited areas would be higher than the original parts so attempting these changes may result in something a little different but that is something that I am not entirely knowledgeable about..
