Excellent work!
Only 3 things i dont like
You "glued" the barrel? on your pic it looks like "sealed" into one position and not able to move up/down?
and you shoulda replace the MG, use medical needle to make a better one :-)
Also, some battle damage would be nice, on front and sides....
othervise, a nice dusty & rusty model ;-)
cheers
