Perterz thanks a lot ^^
A friend told me the same^^ but it seems that the other buildings of the exhibition will not be "overdetailed" so I think I'll let it be like this^^
Thanks a lot Klaus-Dieter, you prefer buildings that open at the back ? but these one will be in a middle of a city for an exhibition done for non-lego fans ( they'll be at a train exhibition ), so I think that these kind of buildings will be more appreciated + as they'll be between rails and road, I think it'll look better if they're totally closed^^
the two trucks will be at the exhibition, I'll put the black one on the road, somewhere ^^
so you like my Yellow sport car ? I love it too, I built it only because... I wanted to! I didn't plan to build it at the beginning, it's just that I found the yellows/oranges slopes I put at the front, and told myself " hey , I can make a car with this! " so I'm glad you like it^^ and I'm quite proud of my little pool too! thanks!
