Very nice.
But I think he'll get in trouble at some point.
It's not legal to sell such products without permission. Using material from copyright productions. It does not fall under "fair use". Some company will sue him at some point, because he's essentially making money on their creations.
Not quite so simple, because there are clauses about derivative works.
That said, these are close enough to be infringing, but just saying.
