I love the detail on the balls, It looks like he's throwing a poisonous fireball.

I also agree with the quirk thing. His quirk is hella underrated considering his balls stick to anything other than Mineta, and they won't come off for a good amount of time. Not only do you have the obvious route (shove it in someone's face and let them suffocate), but by being a little creative, you could also entrap anyone, ranging from regular cuffs to serious back-breaking restraints. In the first OVA, his quirk pinned down All-Might.

Very nice

Wow these ones with the border are nice the white border is pretty good idea and the character really comes out of the box pretty well so nice job there and I like the idea here of the border but maybe you should make the border glow or shine maybe even sparkle somewhat it was pretty good charchter work and detail I like the element here I like the detail if it all and you have done some pretty amazing stuff here with this one

~~SUGGESTED IDEAS~~
More glow on the borders
