Great Job Erik. There may be innaccuracies, but for a 1/72 kit you did a great job and it is hard to expect 1/35 (or 1/16...or heck 1/1) detail on something so small without a LOT of work, so I would not knock yourself too hard about it.
For your next Russian build (

) remember that the tow cables probably would not be strung up on the rear fuel drum supports...they have holders on the hull for them, to keep them out of the way, like on the front glacis. Not saying it could not be that way, just that it is uncommon to see that. No biggie.
I woudl rather end on a positive note, so good job again. Better than anything I have done in 1/72.
