Looks very nice. The cammo scheme is well done.
Points: The tracks are too rusty. Unless this tank has been sitting in a rainstorm for a month, those tracks would be more black and dark brown.
Also, the tow cable would be stiffer...it is a very minor point.
Finally, the MG appears to be more silver than black...maybe it is the photo's? The best finish is to rub the MG and other bare metal, or near so, parts with graphite, like from a pencil.
Hope this helps and keep up with the Russian Armor.
