Very nice work. I would certainly use the WB and cursor set. The only real critique I havew on the WB is that I might recommend maintaining the diagonal curved and squared coerners on all eliments, all the sections of the start menu as well as the program windows and dialogs. But I can't be sure without having seen it both ways. Like I said this is very goood and I would happily use it as is...
Will you be carrying over the cursor look to the toolbar buttons as well, or what do you have in mind for that?
