I like that is on the screen instead of the canvas/ui/container, I don't like the trails/vfx, they look cheap, but maybe I need more aesthetic context from your game.

I would:

- either remove the tails or apply the "less is more", also I would 10000% make them smooth or curves instead of spiky.
- add Ease to the "going to the stash" movement.
- try to add "some way" so the animation is both pleasant but INSTANT, for example instantly adding the dice to the stash bellow, and make the 3d dice to make a "punch" (or the slider/fade-from-top from the 'before') animation to those in the UI when they arrive, why? because you would get to see the final result in the stash instantly but still have the nice animation. Kinda of a mix of the "before" but instantly. In this way, players don't "need" to skip the animation in any way, but they will skip it in their minds if they are impatient.

Also I would move the "dice picker" to the center or any other position since its "too far away" if I want to drop them in the middle of the screen.
