Dani definitely wears the loincloth outfit better than Warren does. You are right about the colors though. Dani does seem to get stuck wearing the same colored costumes a lot.
As for Angel, this another one of feather winged Angel's bad uniforms. The feather winged version of Warren could give even Shadowcat a run for her money in terms of poorly designed uniforms
Seriously about your foot and your dad's fingers dude? I feel bad for you.
I still say metal wings over feather wings.
The metal wings can fold up completely into his back. No need to worry about them getting in the way. I like the idea of him keeping them at all times.
The feathered wings are what cause Angel to be dismissed as just another guy who can fly. There are other X-Men who can fly, and they come with other cool abilities.
The metal wings are the ones that help Warren stand out. They provide him with a better back story also.
