Hi Gary
As a showcase for your items and capabilities I think it is very good but...
and no offence taken I hope, it's my opinion, you need to lose about a third off the length of this scene.
To much space, too long.
Just like the lens on a camera, bring it in tighter, more focused.
Move the tank and the figures over closer to the building and get rid of the second ruin, the one with little left standing.
I've read about your sets, and how you've gone about creating them so they can join together and I think its a great idea.
The only trouble is I can see a repeat pattern on the road. I think it would not be so noticeable if you'd painted and weathered it differently.
Unfortunately you seem to have actually emphasised this pattern to make , certainly to me, more aware of it in a way, by repeatedly highlighting these sections of bricks.
I think also if the road had been used and was quite a busy one you would see tell tale signs of wear in what I would call the trackways, the place where vehicles, carts etc. wheels run, as opposed to the centre and edges of the road. Only subtle, not great troughs but the bricks/sets worn slightly down more.
I hope you don't mind, you did say any comments good or bad
It took me a few seconds to suss out what the circle with two white lines was...d'oh a close up of the detail on your broken timber framework. Nice touch, just a bit difficult for my old brain to fathom at first.
Good luck with the diorama stuff, I think its some of the nicest I've seen.
regards
Alan
