The blink is well done, looks like you had a positive easement in and a negative out. Good eye. The wave confounds me on one detail: left line, near the bottom of the frame, where it reduces to a point. When his hand is up, the angle is quite fat. When it's down, the angle is slim and long. How did you even get that to change? I doubt it was intentional since nobody but an animator would notice such a thing.
