Hello! My name is Gabriel and I'm new to this website, I'd like your help finding the origin of this picture and the photographer
Thank you in advance!

I can't see the photo. Are you sure it was properly uploaded. Anyway maybe you should try searching by image in Google? That feature helped me a lot over the years. Not much of an advice but it takes only a minute to try.
