Oh my gosh this was funny. I don't know who that other guy is, but I'm very familiar with Saitama. The animation was really good and I appreciate the attention to detail of not only key motions leading into impactful motions, but also in expressions, and technical anatomy.
The detail that had to go into the backgrounds, especially when Saitama sent him soaring!
What fps do you have it running at and did you animate on 2s?
