Looks great - you put some great effort and time in the skin
But keep an eye on the memory usage - your skin is using 411MB!, thats why it also took ages to open vlc. The key is to optimize the sliders - by removing them (i just renamed them), your skin is only using 33MB! I had the same problem with my skins -> I found out that the size (height) of the sliders use a lot of memory -> so maybe you can reduce the size of the sliders somehow and remove the eq sliders -> also don't forget the fullscreen slider
Second thing i noticed are the different sizes of the compact and normal mode -> when both windows / frames have the same sizes, you can avoid that you always have to resize the actual frame to the one before.
Also it would be nice if you can maxmize the window via doubleclick on the bottombar (now its only on the topbar) Last but not least the Volume slider could be little bit wider.
Despite all those critics the skin looks great and very accurate
