Second thoughts metallic feel not a necessity. only try if you think you can make it work.
try some more variants of the entry #7 which we have ranked 1 currently. Try different arrangements, and colours. We like the font so keep that the same if possible.
Overall we like the clean, professional and modern look that you've gone for.
