Looks good, mate.
If I can offer some constructive criticism though, I agree with the guy who said the barbs on the wire are too long - makes it look way over scale. I feel the rust colour is a little too red also - tone that down a bit and maybe the oversize barbs won't stand out so much.
Also, the clumps of dry grass look out of place on the nice green turf. Give these a tinge of green also to blend them and reduce the contrast. Look at some real grass for an idea - even drying grass is usually green toward the base.
Love the addition of the guy taking a leak - the pose of this figure is very natural. The bicycle looks good too.
Your '88 under construction looks fabulous. I'm not an armour modeller, but I can appreciate the effort you have put into your work. Well done.
