Thanks so much for the feedback!
The ref from yaoman was super helpful! I actually tried to incorporate a headswing of sorts into the animation, similar to the lizard by Orkimedes. Also tried to give it more blur which I noticed wzl did in his edit (thanks a lot for that btw). A problem that I ran into though, is that I need to shift the feet if I make the head fling back like so.
Perhaps I shouldn't go with the headswinging, but just pull the head back directly, instead of making it swing back, similar to the first version? Or would that be a lazy solution to dealing with the shifting legs?
Also, here's a second version where I toned down on the blur, I'm kind of liking it more than the previous versions -it feels a whole lot more smoove. I'm thinking that I should build upon this animation where he quickly chomps down without building so much blur up. Also, I added a second colour for the teeth blur.

Thanks a lot for pointing that out man! I gave it another go and tried to make it look a tad more exaggerated. It's a subtle difference, but perhaps the head movement isn't nearly so 'jerky' like the first version.
@seisiki
Mmm, that isn't a bad idea, but I think the problem with that would be due to it being a solid colour instead of it being such a small sprite. Maybe I'm wrong though, I can try a few things out!
edit:
quick edit where it's feet stay in the same spot.
I guess moving them will be the only option, assuming I'll keep the head swing movement. Will still fiddle around with it and see what I come up with.
