Hey, I love it, but a couple possible improvements could be made in aesthetics and maybe functionality. The aethstetic aspect i mentioned would be maybe a couple or a few grass block entities in the midst of the particles, it seems kind of hollow and particulate on view, also maybe instead of being at head level the ring extends from the ground to shoulder level, and pops up to head level upon jumping. In terms of functionality, Something I think could add to the moves utility would be; if you rightclick while still charging the ring, you can bring up a little wall, 3 wide & 2-3 tall as a defensive measure. But yeah other than those couple things, I LOVE it, I've always wanted to see a concept like this. Beautiful.
