PowerLine

I actually like this. It is simple and clean. I almost see a power button in the middle of the symbol.

Good job! the only thing i would say is that everything looks pretty tight together, try loosening it up a bit, especially on you sub text, its too close to the main text. Just as a little rule of my own i tend to use the Caps height of the sub text as the spacing on how far away it should be from from the main logo text. Sometime it still doesn't look enough of a space though and needs some minor adjustment but its definitely a good starting point. Your symbol could also do with being moved up a little bit too

I agree with M@... great design, you just need to give it a little room to breath.

Good job. Got nothing to add to the above said.
