With all due respect to George Perez, his style just doesn't click with my view of Wildstorm. Jim Lee, John Cassaday, Doug Mankhe, and Ed McGuinness strike me as being Wildstorm. There's a certain oval-ness to Perez's style, where as the others have a more square-rectangle style. Hard to describe.
Not that it matters, since I don't buy Wildstorm stuff anymore. It just looks odd to me.
