Hi felix thanks very much.....
I used a few of the new features in zbrush for the wings..... firstly I drew out the forms in black and white using the quick sketch page... here you can draw in symmetry which photoshop still have not cottoned on to!?
so there i roughed them out then I used half of the design in shadowbox so by drawing out that black and white image i then get a fast slim complex mesh perfect for a wing..... shadow box feels like a huge breakthrough for mesh design! shadow box feature shown here.....

with this I use a bit of polypaint to separate into groups..... then apply group loops..... mask the loops and that provided the details..... a couple of great tutorials for that type of work are here on the pixologic tutorial page.....
