This is my first attempt at an armor piece. This model was built about 3 years ago now. It was not a fun build as I managed to lose the turret end piece and the tracks gave me fits beyond belief. I'm also not happy with the weathering I did on the MBT either.
As y'all can see, I have a VERY long way to go before my work looks as good as the work posted here.
Anyways, any input on what I can do to enhance my skills, especially weathering, would be greatly appreciated.

Well, the first thing is that the weathering is way too excessive. I don't think that a modern vehicle would have that much rust on it. Other than that, look around the site for a lot of tips and tricks.
