I honestly have no idea what this is even about. A man, paranoid about the existence of dinosaurs, and confident in his belief that he can't turn into one... and a picture of a fat man against the floor.
The lip sync seems alright, but the way the mouth itself moves seems choppy. The animation of the man is rigid and even a bit erratic, but with the hand and body movements you convey the emotion pretty well. Nice job on the face expressions too, you can see the utter paranoia and deeper conflict this man is suffering. Background is plain and boring, not gonna lie. Maybe they could be inside a house, or an interrogation room, idk.
I don't know what the hell this but you've got potential. Good luck on the future competitions and improving your skills!
