Brooklyn Beckham took a break on the sidewalk, looking a little spent, as he seemed to be waiting for someone outside the fashion school he's attending.

Brooklyn is a student at the famed Parsons School of Design in NYC where he's studying photography.

He also just released his first book, "What I See" ... a photography book, mostly pics from his phone with captions.

The photog says Brooklyn was waiting for Mom Victoria, who picked him up and took him to lunch.
