Yeah I'm pretty new to pixel art animations so I used a Gomez spritesheet as a reference.
Instantly saw Gomez as well... Also, as skeddles already pointed out, you might want to hold the eyes and mouth in one place. I know you said he's supposed to be derpy, but it just might make more sense to do just the eyes instead of the eyes and the mouth. Right now it's sort of distracting and doesn't look intentional.
Now that atpalicis said that it does look a bit like the FEZ character. It's quite similar but still good!
Is it inspired/ripped from animations of Gomez (the main character in FEZ game)?
