Okay, I do nto know what to think of you, becuase it seems you can make everything!
The SU looks fantastic at this stage, the modulation is frankly well done technically but with very excellent good taste too. Boy, this tank is really sweet to me. I love the grass on tracks too, a very nice detail that will look dramatic once coloured. Well done.
PS: My only advice --> run away of simmetry and paint things diferently on both sides.
