Motion blur is meant to make the movements look smooth. It's not meant to make things more difficult to see, if you're doing that then it's kind of ironic
If you're too lazy to make something look good then don't do it at all jeez
Imo the cc just looked like you made everything less visible and more transparent (Other than diffusion)
Yeah lots of parts were choppy and stuff
Don't diss people for cnc-ing your work regardless of their skill in videomaking, you don't make a movie then call everyone who doesn't like it stupid because they can't make movies themselves. Just listen, whether you want to improve or not based on their opinions is your own decision
