1) in the title bar buttons, remove that little bit that extends below the rest. im referring the the niche under the minimize button.

2) try using the yellow/black stripes from isync. i think they look a bit nicer than yours. (theres another thread around here about that)

3) something about the "bolts"(dots) just looks wrong to me. not sure what though. might just be the image compression.

otherwise, nice looking theme. especially the red highlights.
