Does not seem to be a model for a larger piece

I notice you didn't put the same comment on the other model plane Kyricom

I have to agree with Kyricom.......maquettes are usually a scale model of something that is going to be built or made. I don't really see a full size version of this being built. Just my opinion of course!

Wiki Definition: A maquette (French word for scale model, sometimes referred to by the Italian names plastico or modello) is a small scale model or rough draft of an unfinished architectural work or a sculpture.

It is used to visualize and test shapes and ideas without incurring the cost and effort of producing a full scale product.

This being the case - consider it the rough draught as per the definition.

I think if you are going to say that an entry is off theme, the least you can do is be consistent and not write "nice entry GL" on one and "off theme" on another and further - if you think an entry is off theme you should try and red flag it instead of discussing administrative issues on entries
