Looking nice anonymous_alcoho.
It's not the first time that I've seen your work but I can
already say that the tank is going to look really good.
You used a referencing image which is very common to model a 3D object but not as easy as many people think
Just some tiretracks and some nice skins and you have your self an amazing tank !!
When you've accomplished all those features, be sure to expect my C&C

Cheers
