first of all thank you guys for the compliments!
@Borjacho: to be honest I don't count how many hours I spent on this project, because I usually work on a couple of models a time, in order to not boring me.
I think I finish this model in 200 hours less or more
@voyageur and Luis: this model is for my own collection, there is no chance to see that model as a Scuderia issue.
