Really nice one armogeden!! Something what doesn't match have other people told.
But I would doesn't send it to Nike. As REyRey said, big companys working together with agencies who making the whole concept.
But when you send it, it's possible they use it without your known. For example, a friend of mine have designed a table concept, and visualized it to IKEA. They said "no thanks".
One year later he have seen this table in the new IKEA Catalog
Many similar examples exists with clothes from fameless designers and H&M.
Anyhow... great illustration!
