Yeah, I'm sure everyone has seen something like this a hundred times. However, for ME this was an exciting step because despite all the kits I make, dioramas I created, etc.... I have never done any diorama that needed any sort of landscaping! This was a relatively simple first try. I used a 1/2 MDF board as my base so I could recess the building, Under the MDF is a masonite board so there is a visible floor. The smooth side is face down so it can slide around on a shelf easily. A couple strips of wood for stairs and surround. Covered up gaps between dome and MDF with putty. Then came new territory. I first used Aleema's Tacky glue (which I think may be like Hodge Podge) and tossed some diorama sand on it. Brushed of what wasn't sticking. Did that a few times. Nice thing is the sand was the same color as the MDF so any showing wouldn't even be noticed. I then did a few more dustings of sand with spray glue made for dioramas. Another dusting with a finer, lighter color of sand. The barrels, crates, generator, and droid are Hole in the Ground kits
Nice to gain some experience where any errors would be minimal or fixable.
