Well there are several things i like about this build...
The ground work is great and the chopped logs on the back side are a fine touch. They really help to fill in the space, good job there.
The figures have all the flashing/seams sanded smooth, great job. And all the joints are smooth as well, very nice. In fact you should be very proud, as old as the kit is you make it look like brand new.
The only thing I would add (And you might have and I just cant see it), is a little light drybrushing to the gun. Just to bring out some of the detail.
Of course thats optional.
All around great build, thanks for sharing.
