Hipantsless!
I built the tank and it's a wonderfull kit!
Dont worry about the track's they are fine and the gun elivation looks just right. I had a problem with the lower part of the mantlet, a very big gap. So I took a piece of cloth (Yes I know it's uncommon...) used filler and super glue to shape and blend a the new lower canvas into the upper plastic, causing it to look like a one piece canvas, and the best part is that now the gun is a bit more elivated!! Ok no hoitzer but sure looks nice.
Very important part is the small hatch on the left side of the turret. it is blended in to the turret and not just stuck there.
Try to obtain photos of the area, you'll see the diffrence.
Good luck, and good luck with the color!
