I'm a modelmaker. I spend all day in work making models from scratch for all types of reasons. If that guy Macfarlane thinks the models in those pics are realistic then he needs to check his scale ruler again. The figures are way too small for most of the surroundings they have been placed in. Check the size of the holes in the chainlink fence..the sheer hugeness of the door in the tower, the over sized crash rail on the road side....I could go on.
I guess there will be a market for them but anyone who already makes their own models will notice the figures are about 25% to small as they are. the paint finish on them is just ok if you are a wargamer type of painter but he doesn't say if they are prepainted or the builder has to paint them. The Lego grid system suits the Lego world but when was the last time you saw asphalt laid in a grid in a realistic model.
He sounds like he is expecting people to by his stuff and use it with their existing Lego system but i don't see that happening. If i wanted my Lego floors to look more realistic and like old worn wooden planks it would be real easy to do. But then they are stuck being planks. If he thinks model Makers will buy his stuff and combine it with Lego to make dioramas, he has another problem, and that goes back to scale. The average door in the real world measures just a tad under 2 meters high (2000mm) the average Lego door is 57mm high, 2000 / 57=35.08 so giving a scale of 1:35. There are no model production companies that work to that scale so getting extra accessories to suit your diorama would be next to impossible unless you scratch build them yourself. So if you have to build the stuff anyway, why bother buying the stuff in the first place? Makes no sense to me.
I don't think he realizes just how fussy model makers can be, and as a fussy builder i already know i would have no use for any of the stuff I've seen in those pictures.
