For Ike:
Maybe change the hair texture and eye textures back to their defaults if you messed with them? Can't quite tell from the screens, but it looks like his hair is more purple.
Maybe change the colour of the boots to be more like his shoulder pad / chest pad thing too, a bit more brown would look quite good on this texture I think.
And finally as Xeno said, tweak the saturation.
For Wario:
First of all, don't change Wario's logo to that old M. P:M doesn't even use that logo anymore, so it'd be unfitting to use such an old thing for a Project M recolour project.
Second, is the goal of this texture to make a purple Wario costume, or a black one? This applies to a few other textures in the Mirage series, you guys should choose a main colour and make it stick out. As a good example, on PK-Thunder's Ike, at a glance you can clearly tell it's a purple Ike since there are no competing colours, and the other colours there (brown, blue) are subtle and help compliment the main body. With Wario, the purple and black are very similar, making neither stick out. The shoes should be a different colour too, you can barely tell they're separate.
Finally, make sure not to add random bits of white into the texture as well. It sticks out yes, but not in a good way. It's bringing more attention to the white bits than the rest of the texture as it is now.
For reference, here are the Brawl colours:
Notice how the colour of the shirt and overalls are different, yet contrast well in a way that they compliment each other? Try a colour that isn't black on the overalls, and maybe brighten up the purple on his shirt / cap a bit.
