Ok, I thought I'd get the ball rolling here.

Many of the anime-themed skins I don't like. Most just have headshots of the cast. I don't know about the rest of you, but I don't really like faces on my interface panel. Here's one I found that stands out among them; it has a nice design and caters to the theme without jumbling the control panel.

Here's one more I found. It has faces but they're subtle enough that they don't jumble the skin at all. I like the soft color also.

Personally, I don't consider Transformers to be anime - maybe I'm a purist
but it didn't start out as anime. It has become so however, so I don't think this is out of place here.
