Professional or too KPT?

What do you think I need to change here?

Maybe just not the bevel in the objects as much as it is. Maybe not as diverse just tone down a little. ( but what would i know i am a newbie)
Looks cool though

Definatly tone down the bevels.

i would throw a little bit more color in there. its way too flat. plus, we've seen this blueish-greenish-grayish shiny metal look a million times before.

Well I don't think the bevel looks totally bad, I think it would look nice if you were going for a more plastic(y) look.

But the way you have the things set up on the bottom rectangle, the bevel is too much. But if you were to move the things on the top inside the bevel, then it may not look so bad.

Not the most original idea but I think its still neat. I think it would look better if you blurred the edges to make them look smooth or something

I would keep the top left image and buttons but make the rest of the stuff flat because that is overdone with bevel

is that better?

a little yes. The big bevels still bother me a little, but its not really about pleasing me or anyone else but yourself. If you are satisfied with it, go for it.
