The statue of Liberty is not a building nor is the Washington Monument even though both have stairs and an observation platform neither one is classified as a building. Your Guitar is too small for people to enter in any case. It's more like a statue and not an example of roadside architecture.

But its inside a building dont you think? Thats why i call it ancient its old and just a few of rocks left from the original one. Anything that you can be inside is a building, anyway i going to change the guitar . But i keep my point of view.

Well now you've completely changed the image. Just to help you understand, the guitar being inside a building doesn't make it a building. You could have made a larger guitar big enough for people to go inside with doors and windows and that would have been a building.

Thanks now i get the point of the contest, im working on a giant guitar now xD
