Nice skin. Great job!
I like the overall look as well as some of the smaller details, especially the Posbar shape and the shuf/rep & on/auto buttons. It has a bit of a retro flair, methinks.
Two things I would change:
1) make the border of your Megamen in the Mbinner black instead of white (or even red)
2) the titlebars/winshade bars. They are very well made and look great on their own, but I don't think they blend in well with the tri-chromatic theme of the overall skin. They might if you were to introduce more metal elements in the windows, or make the metal borders thicker, but as for now I just don't think they're consistent.
But that's just me.
