Artwork was alright, but least of the worries.
You got artwork down, animation could have gone better, more frames and such. The emperor farting wasn't to my liking, just seemed like a lame joke. However, the guard's neck extending like it did made me laugh, that was good. Voices need great improvement, and the sounds/sound effects are off by a second or less. That may annoy some people.
You still did fairly well, and you do have some good jokes in there.
