Thanks guys. I'm sorry too, I'd like to finish, but... I had to go after money. It's the free lancer life... I was some time without job, and I had to go after some money. Because this things here in the challenge didn't advanced. It's a pitty... but I still have intentions to finish my model in the future.
But I'm well guys, thanks again for you kindness. Let's see what next challenge deserves for us...
