The skin you are pointing at is specific for the Blogger blog. That'sa different brand and you cannot get it to work on B2evo.

The only thing you could do is edit an existing B2evo skin to look like your favorite as much as possible. Tis is not easy though and will take even an experienced skinmaker quite some time.

Have a look at the [url=http://skins.b2evolution.net/]skincollection from B2vo[/url] and [url=http://www.b2evoskins.com/index.php?blog=5]here[/url].

Good luck

Adding onto what afwas has said, you can also request for the skin to be made here http://forums.b2evolution.net/viewtopic.php?t=12091
