you are advancing well! but it seems not very usable if you dont make it with realtime parameters! Now everytime you want to see what you have done is to generate the model and if you dont ike it you must start again!BTW, why you dont use the BlenderArtists forums - there are meany people that are willing to help!
I just discovered your blog and your work is amazing!I suggest you to try voronoid patterns for the wings, will look more natural and organic.
Well, I have to know how to make voronoi pattern 'mesh' shape.
