The rough animation is done. But there are still some improvements that I could do, like that foot in animation 2 - it looks horrendous XD.
Then there's the abs part of the bottom in animation 3. It's not consistent with the other frames. Also, I want to make his animation a bit snappier, like when the vlogger thrusts, the bottom's upper body leans back slightly then swiftly bounces back to its original position in frame 1.
As for animation 1, the position of the hips part is unclear to me.
