Skin looks fantastic, one of the best I've seen posted here on VB.org. Congrats.
There are only a couple little things that are minor, but I would've done differently. One is the reflection underneath the menu options (Home, Gallery...). It tends to throw off the text for me. I would've made them lighter. Also, I've never been a fan of image signatures, especially when using postbit instead of postbit_legacy. Too many horizontal things confuses people (or just me!). So I would discourage image signatures.
Otherwise things look great

I intend on signing up, I'll be sure to mention if I catch anything else.
