Wow. I love the concept, and the thought put into the effect. I'll admit, it's unique and as soon as I saw it, I was like, "Bingo. That's the main menu!"
Now, there are a couple comments. First, the font you used it nice, however fonts are something you need to be careful with. If you wouldn't mind, can you check the licenese on the font, and make sure it's free for use in commercial projects? It's something I really don't want to get in trouble for, and trust me, you can.
Second thing. the left hand side does need some sort of texture, or some detail, or something. It's a tad to bland.
When this is implimented, I would love to see the viewport actually be translucent (only containing the reflection), and have a 3D rendered scene (which changes randomly) so you see things moving behind the glass.
Final comment: that picture looks to me like it's the cargo bay from star trek. (am I right?) It would need to be your own work there, honestly. If you would like, however, we could do up some nice sketches of a room for you so you're not doing everything by scratch. However, that can eb doen latter.
Actually, I had a minor thought. Maybe you could border the entire thing like it's being displayed on a console, or a terminal... Not sure. Just a random thought.
Also... planning on entering the HUD contest? :P
