The separators do look fuzzy, I would sharpen them up some. As for the docks themselves, I like them. The running Indicators look great, reminds me of an LED display on a radio's equalizer or the front of my router. I would go with "LED Docks" for name.
Also possibly for the spacers try making them thinner and touch from inside edge to inside edge *of the black area* or maybe leave a pixel or 2 at each end, and make them slightly taper thinner toward the rear, possibly making the separators look more like a light bar within the surface of the docks. Kind of like radios have, displays with the lights built in to the plastic that you cant see til they light up.
Yeh I know, i get tons of ideas in my head and ramble on..
Keep up the great work.
