DW88 if you come back have a look at this tut as it will give you a bit more info on what you can do. Looking at your Spur's drawing drawing which you posted you could start off using say the Arc Warp and then move to the curtain tut using the proper Gradient Mesh Tool.

Come back again if you want more help.
