Daft Punk helmet model and tutorial

Daft Punk helmet... I was asked to make this model and to make tutorial how to make it, so here is model and tutorial you can find on my blog http://cad-unigraphics-projects.blogspot.com/2011/08/daft-punk-helmet-design-tutorial.html just be patient, post have 81 .jpg so it is little slow to open. I hope to hear your suggestions both on model "how to" and on format of tutorial.
