The feathers are the right shape, but they look completely different from the bird and don''t belong on the same shirt together. I actually like the look of the feathers more than the bird. Maybe rethink the bird.
it appears that the trajectory of the bird in this version is such that the feathers are under him, whereas in V1 the feathers seemed to be a bit more behind him (which i prefer). i think this is due to the fact that the bird is a little larger since version 1 and maybe he's pointed up slightly less.
i also think that the feathers in v2 best match the language of the glowing white bird shown here. i like this new glowing white bird, by the way.
