@ cute heart: your idea is solid and a good one, but you seem to be lacking follow through, the great thing about design is well ................ you design it how you want it, there are no restrictions in art but your own imagination. Your bars ( highlights ) should not be soo big, as long as the menu text can be seen on bars thats enough, me I go 2 pixels from bootom and top usually, especially if i going to really do detialed bars, and want to create an illusion of depth on a 2D object. I often utilize those extra spaces of pixels for adding drop shadows, or deeper shapes etc as i said anything goes

so here is a quick list of what i would personally do to your theme to spruce it up a bit.
1 - I would make the clock animation smaller maybe 30% smaller, this would allow for both your clock and the themes digital clock to be seen easily. also it would allow the operator text to be seen.
2 - on your highlights as stated earlier I would make highlights not so big, and I would also change the heart graphic from being stretched to being even sized maybe 20 by 20 px, and placed on the end of each highlight, this means text can be easily seen. Plus it will look a lot better than currently.
3 - think more about your themes color pallet, if your main colors are to be black and red, then choose similar colors for other details, like make the scroll bar red, and make your text white for screens, cause white can be easily read on a dark surface, and make the scroll bar background black, for a black background, with a nice red scroll bar will look great, and totally fit in with your themes appearance and style.
4 - When ever you wish to use a busy image on the navigation content, try this little trick.
make your image the first layer, then add a new layer next select all of the new layer by using ctrl A , and then fill it in with flat black #000000, next go to your new layers blending properties and change the overall layer opacity ( first option at top in menu ) to say 70 or 80% , this will allow you to still visabley see your image, while adding enough cover to now also see any text written over it

All of what I have said may seem hard or confusing for you now, but given some time and practice, will become common sense in newer projects etc, it all comes with time ( don't believe me go see my older work lol )
so yea just rememebr it's your theme there are no set boudries in how you go about skinning, and it is this that sets each designer apart, sure being skilled at digital art helps, but it's not everything, imagination is

best of luck
