A very nice "model" in "mini-Lego". Rendering is fine but it would have been more logical to put at least two attachment points to secure the 2 tanks to the main tank. This would have given more stability to the whole, because it is a very "fragile" model. Additional parts does not allow for such a change. Moreover, this is not unique to this model, but a general criticism against Nanoblock Products: it would be desirable to make the brand manufacture its parts from Japan rather than China because the bricks often lack "d 'hangs' and come off easily, especially smaller 1x1 or 2x1.
