It’s pretty much just the winglike hair tbh, plus white color palette and open-chestedness
Lucas and Kamina from Gurren Lagann
For this one the glasses really stand out to me. Also the hair (part of it combed back, part of it sticking out front), and the open-chestedness again.
Elliot and Terunosuke Miyamoto from Jojo
This one was a bit of a stretch tbh, the only things that stick out to me are the long coat, color palette, and paper motif (Terunosuke’s power involves folding paper; Elliot’s art has the origami cranes and scattered papers).
