Hi Doan!
First of all, thanks for sharing your T-62! You have done a great job on the painting and I like your weathering style. I do see some small things that you maybe want to improve?
-missing light on turret
-small seam lines on headlightcovers front hull
-the damage on the mud guards (front)is to my opinion a bit to much. You would expect a more beaten up look, and probably the mud guards would be missing already when they suffered this damage.
-Not all roadwheels are flat on the ground? They do seem a bit misaligned?
-maybe you can add some subtile dust areas (very little) to break the green colour.
Don't get me wrong, I really like your vehicle though! Just some things I spotted.
Cheers,
Jurjen
