I think when he started on WW, that's all he was doing. It wasn't until over a year later he started writing and penciling the New Gods. I had been reading the Bill Loebs run and remember the change being very jarring — not only the costume tweaks, but growing her hair longer than it had ever been only one issue after it was cropped short. He also started having some severe proportional issues in his figures at that time, and was also when he started doing that weird splayed finger garbage that he still does.
