Good for a first attempt.
It's probably gonna be weird listening to me reviewing your piece since we have talked so many times in different places, so be aware, I'm about to appear as a whole new person.
The piece overall is funny, not much Pac-Man art on this site so it's a nice change of pace. I prefer the art you used for Pac-Man much more than the art on Blinky. You used good symmetry on Pac-Man, but Blinky, especially on his finger and his bottom, lacks proportion. It looks more like jagged lines than what the ghosts from the game are appeared to look like.
Another thing I noticed was the distance the pellets are from each other. I know it's a minuscule detail, but I have to be nit-picky in many of these areas. It's more noticeable than you would think, but just a simple change in width can fix that up quick. In the end, it's a good piece of art, funny concept and nicely done overall. Keep up the nice work and I HOPE THIS REVIEW DOESN'T AFFECT OUR FRIENDSHIP!!
