Since you're definitely not short of praise, I hope you don't mind if I toss in a bit of skepticism. I'd hate to build a gargantuan tank (on which I would spend thousands [or at least more than a thousand] of dollars), and then neglect to add a single scratch, chip, or speck of dust. Of course that's your own personal opinion, but to me, the fundamental aspect of armor modeling is the addition of weathering and wear. Yes, you've done some fine shading, but it still looks like it just rolled off of the assembly line- well, it does besides the rust on the tracks, which looks a bit out of place. Some might feel that the size of the tank compensates for the lack of depth in the paint job, but I for one do not.
