love the style, it can create a great mood working from a black canvas. (tip to everyone: try changing your canvas color to create different moods, it will affect your palette choice as the colors will be perceived by the eye differently)
agree with helm on this one, it looks great as is.
helm: i see what you say about the l-gap, but this also is used nicely to create a shimmering plastic or metal look. Closing the gap would dull down the shine somewhat.
i think the second/third darkest red shade needs tweaking to maximise efficiency, looks great though.
i would also say to get the full effect of this, a full black screen preview in photoshop is in order, with the lights out at night time. it makes images like this truly shine.
