Every animation needs a base loop, even if you're doing an animation that is not,in fact, a LOOP, the base loop is the point of reference and where you can see how is the dynamic, movemente, speed, etc. I usually don't touch on the base loop when it is done, If i need to move them i'll just use other bones or create another parent, so the curve mov. of them is not messed. This one still needs a lot of tweaks,to give "impact", the speed and etc, but the base loop for this animation will be basically this, even when i'll change the position or the flow. But even in this state, just add some camera mov. , some air effect and a sound, boom, the aestetic just changes, this is what most NSFW animators do, but i want to always do something with more detail, i don't want to do animations with 20 frames and say it is "good", but for most people just this is enough. This is the first step for this one, I'll post gifs/videos like this every time i do some significant change.
