Zodiaq~....I openned your taskbar.bmp in the BluePearl WB skin and compared it with every image in the other skin and quite frankly cannot see any connection at all.
Sure, they are both a 'similar' blue with a 'similar' shiny finish, and yes, if you were so inclined you might manipulate one far enough to look like the other...just like if you apply a black fill to a white square you make the square black.....but that doesn't mean the blck and white squares are the same or even came from the same source..
It'd be easier to make the buttons yourself than to bother manipulating another's as much as these would need to be done.
If these works are from the same source, then probably 50% of the WB skins are from the same source....since so many of them have 'shiny' 'blue' buttons.

Sorry, but I'm betting there are other skins out there far closer to yours than this one...and very likely none are 'rips'.
The last issue I had to argue to convince someone of a ripped work on another site was to do with this site's Universe Metal theme....[a skin graphic I'd just been adapting myself so I knew it VERY well]...and the colour picks were IDENTICAL at every salient point which is purely impossible to fluke as there are 255x255x255 different colours....and the only difference was one image was a 256 colour gif and the other was a true colour jpg.
Unless I have got the wrong skins and images...[I referrred to the skins in the email]....this is not a case of ripping...
