Hmmm...I'm so torn about how to comment on these latest "minimalist" builds...
Vespa Boy, you are no doubt a VERY talented miniaturist; I say "miniaturist" because you are obviously extremely adept at producing miniature versions of terrain features that most people would never even consider attempting to reproduce. What you do is really, honestly, perfectly unique--I've never seen anyone display builds like these.
It's obvious that you put a lot of time, thought, and effort into your builds. You can see it in your work. The little details (what I personally would NEVER even consider to model, i.e., I would miss them completely) are impressive in your depiction and weathering. You are to be commended, and I do enjoy seeing what the ^%#*@ weird creation you've come up with next!
But I also can see why some of the guys here are less receptive; it's just not really a "diorama" as such as we know it. Say "diorama" to me, and I think "storyline", "action", --something that draws me into a moment in time. I know you'll stand by the dictionary definition that you posted here on the other post, but I agree with Arty (Gino) on the opinion that these aren't really "Dioramas" in the sense that we expect them. Does that mean we're "right"? Not at all! But again, we all have our opinions, and I guess what I'm trying to say is that, you might have to expect a little bit of resistance to what you've posted here simply because it breaks all conventional rules. I don't want to see you go anywhere though; your work is too eclecticly weird and special to lose.
But if I could recommend something? THINK BIG, man! It'd be so cool to see you attempt to tackle something like an actual architectural structure, or feature like an old castle wall or mosaic floor! Have you ever thought of something along that line?
BTW, I will say that you've caused me to reconsider what my definition of a diorama actually is...I'm wrestling with it right now on my living room floor, beatin' the tar out of it!
