I like the black cat. Maybe some grey lines would improve it, but it looks good to me now.
I agree with the comments about the phrase at the bottom:
Chip and a Chair doesn't go with the cat.
The font is hard to read.
I liked the "got fish?" idea...
Otherwise..
"Do you feel lucky?"
"Don't be a *****"
You might reduce the contrast on the bullseye background. As it is, it distracts too much from the foreground.
With the black cat, you could try just putting a single white denom right on top of the cat. That would also leave room to wrap a phrase around the bottom of the chip.
