I enjoy looking at the different expressions, as well as how some of the movements look.
Definitely work on making the movement smoother & less stiff because I know you can do it, I can tell from parts like the start with the fly getting caught and when the tongue pulls your character forward it looks pretty good so I have faith you could do it throughout the whole thing next time.
Keep making more because I'd love to see how you improve and will eventually make some really neato burrito stuff, hope the best for ya :>
