Spinning prop and candle-flicker effects in the explosion... about as far as I can take this for now - waiting for some vehicle kits to populate the base (Pit-Road 1/144 for a little forced-perspective)
Testing with the convoy vehicles after priming but before they are painted and finished. The 1:72 - 1:120 forced perspective seems to work pretty well, no?
Some updated shots with the new convoy vehicles and a re-scaled "explosion" to suit. The 1:72 to 1:144 forced-perspective seems to work even better; even closer to the box art.
