Ok I guess I'll be the odd ball here.
I'm not a huge fan of this design. I'm not sure where the word "Sleek" came in to play here, because IMO this design is anything but sleek.
The blue text on the buttons, are a big no no, unless you plan to completely stylize the buttons. It makes them hard to read. By all means however, please do not change the button text to orange.
I agree with Dubs. There is far too much orange.
Sorry to bring a sense of honesty to this thread along with dubs here, but I figured that's what you wanted.
