Love your work man!
Critique, I do think the color pallet could have been a little stronger, The farty bags seemed not to belong in the environment of the green grass. It's like they were too evenly colored all throughout the film.
The spittle was great. Love the idea and concept for a character.
You're skills almost want to make me crush my hand in a steel mill accident so I can sit at home and draw all day... yes... I must make this happen. Then hopefully I animate farty bags as well as you!!
