I reckon that's pretty damn fine, and using your rail layout as a backdrop is inspired! I've been tempted more than once with this tank, and your build tempts me even more! Nice one.
Thanks i find it is hard to know when to stop weathering I seem to leave it and go back after a day or two and add more this was hard as I had a picture in my head of what I wanted which turns out was far more than my skills could achieve. I did enjoy just brush painting for a change.
Plus with this kit it is fun to switch it on and play tank.
