Festa,

If you were looking for responses (say "criticism" too - even if a not necessarily bad manner) you've come to the right place! Good you're here and come back more often!

Well, about the fan: It is a really nice model, sincerely! However if I could give you an advice: don't use simple lines even for very thin "wires" or whatever they are on one side of your model. They disappear when you turn profiles and edges off. Surely you can say you don't want to turn them off but other people may and also, if you would ever go into a more serios rendering programme (unless you have already), they will just disregard lines like that and you'll end up without tehm though in a beautiful picture!

Of course this is just my opinion - others may thing differently.

Have fun; Gai...
