Sorry I haven´t skinned with WB yet myself. In 1 week i learned to create 4 autohiding bars all around the screen including task bar and system tray, a nicer clock with an old public version of objectbar. Their new plus version is displayed in an awesome 21 minute, 57 MB video. It was feasible with the old version, I managed to skin those bars to look like a jungle with skin studio public those days.
If I had a permit and time, I would combine the skin with the looks you like with my own object bars I would reskin with skin studio. Then I would, for a starter, only learn how to change the start menu with WB, which should not take that long in opposite to creating an entire new skin. If you dont upload it, maybe you can alter the skin for your private use. I had to reskin all 60 beatnik skins to german 24hour settings and the seconds I love and need. Learned that in a week. Just cant upload without permit, who cares; my bars were full of nothing but my own icons and shortcuts anyway.

Most skinners around there are friendly and helpful, too.
