PeterS,
Just a few observations:
BIG BLUE
1) Remove the icons aside the "Download", "Overview", "User Guide" and "FAQ" links. If you've told the visitor where to go with written words, why give confusing visual clues as well?
2) The 'MEDIA JUKEBOX' font in the upper left corner looks skinny and weak. Use the font that is faded in the upper right corner instead.
3) The screenshot is functional, but boring. there must be something better...
4) Be careful about placing links along the left pane and the header. You only stand to confuse visitors.
METALLIC
1) The whole 'pipe-looking' design is so overused. Please don't lend to its profusion.
2) I assume the features to the right of the screenshot are just features, not links. They look like links though.
3) You shouldn't change colors schemes without contemplating how this effects branding. Be careful.
4) Keep the "Download Media Jukebox" button. I like it, simply because I don't have to search for a download. It also makes me believe you're not hiding anything.
