Anyway, here you go:
Some notes:
- Image's deliberately saved in PNG to help save space (although I'll admit the real reason for doing so is because I prefer it over BMP). You may need to convert the image first before using it in the game, something that should be very easy.
- The shoes of Nega-Lime and PK has been recolored to keep them in-character. They're supposed to dress entirely in their main color motif, shoes included.
- The sprite artstyle and resolution chosen for PK meant he couldn't be depicted within the default outfit for him. Still, did what I could.
- Redone the markings on Nega-Lime's face in an attempt to properly portray what you said about them. Hope you'll like it.
- I gave PK and Nega-Lime brown eyes to help better match their official design. If you prefer the green eyes, shouldn't be too hard to edit them over theirs.
Anyway, I'll use it if Ariana's okay with it.
