Thanks to all of you for your nice comments, that's encouraging!
Amazing!
But this is a question that has been bugging me for some time.
and everytime I think I have the answer, I dont...
So what is Steam-Punk? 
Well, I'm not a specialist, but to sumerize, let's say that it is a mixed from victorian style and modern style, most likely futuristic... According to me, what you could see in some drawings in most of Jules Vernes's books are showing some kind of what could be called "steam Punk". During victorian time, there was a lot of steam machines that were used... using those machine but adding some modern parts should at the end turn out something like what I have created... Copper, iron, wood are materials that are mostly used.
I'm pretty sure that you could find much more information about that style on google than what I could explain here...
Anyway, this style is something really fun when it comes to playm's... lot of things can be done!
I'm doing some other small things that I will show you in the future....
