Advice on a UI I made recently?

[Vynatu]

Made a UI for someone; didn't get chosen by the customer. Realism isn't my specialty, but I like to do Sythe graphics for some 07 gold on the side of my freelancing/etc. Feel free to critique as harshly as you want, give visual examples, etc. If your advice is constructive and helpful, I'll make changes and upload on here.

The reason it didn't get approved is because its a little to blue on most of the text. Either lower the opacity of the lighting or play with the levels a bit. It looks really nice though, good job.
