Gave the signature and avatar a shot, myself.
I wouldn't want to ask for more than 150fg for both if you decide to use them.
Tried to stick to your request of clean and simple with no border for the signature. Hopefully the text is cartoony enough for you. I wanted to keep the sharper Knuckles theming with the font as well. Let me know what you think. Might be a little tall for a signature, but I wasn't sure how else to fit the whole character in with the idea without borders.
If you end up liking it but want it shorter, I can give it a change to be just his head.

And the avatar - simple face with a circle border:
