Hi Kanuni, now I can begin with some comments on your themes.
First try to keep the same colors and tones on all screens for to have a good color balance. (e.g. your popup background color is different in your latest theme.)
Second, try to adjust the height of your highlight bars according to its style. Means, if you use plain bars as you do at the latest theme cut up to two pixels from top and the bottom. It will suit much more better.
Third, try to avoid using text on the backgrounds of the bars. It will lead to unfunctionality, and when you make transparent or semitransparent bars be sure about readability.
Keep on theming, and try to establish your own style.
Btw, I like most the Istanbul theme.
