IAAB draws very similar anims, frequently his characterstanding on one side of the frame looking to the other side doing something vaguely wacky, with another character standing opposite him reacting. I find the faces he draws to be odd. The cheek is large creating a lot of space, but the faces are all budged up to the other side. And the mouth with the simpsons over I would talk about his progress here, but since he has quite an Inconsistent style, its hard to pick out actual improvement. I will say that his current art looks better than his older art. My personal main issue with IAAB is that he is considered hilarious, but personally I find that he relies too heavily on memes and trends, but that's personal preference. My advice is to get creative with more realistic poses, since currently they seem to be either standing normally or doing some wacky cartoon thing. I'd also say to try putting characters at different angles, and try using the canvas to represent a more 3d shape.
