The gradient stroke was blurry at the original size (199x190), but seems to have fixed itself when I resized it.
Edit: changed to blue, simplified outer stroke: http://i47.tinypic.com/6pvllu.png
The gradient is bleh. It just cuts from white to blue. Like no transition. Doesn't really look like the glossy or glassy effect I think you were going for.
Well done. :)
My suggestions:
Maybe curve the line in the middle of the K so it's going downwards.
Change the drop shadow on the K so that it stays the same all the way around it. It looks much lighter and transparent on the top-half.
