Fun little short
That was more entertaining than I was originally anticipating it. As others have said, he does blend in well with that scene. The lip synching was a bit off sometimes. Not sure if it was a technical issue with the animation falling behind on the video or if you had your keyframes a few clicks off, but it was off at times which was kinda annoying.
Overall, good job and good choice of movie. I'd be interested to see more of these things. Resevior dogs is one of my favorite movies
