This is classic Picasso...his early work from Blue and Rose Period 1900s and you can see his Renaissance influence plus his take on "realism cubism". I do see Cezanne too and maybe a Broque in this as well.
He was on Cezanne heavy. His background was all Cezanne.
The cubism on the harlequin’s costume is definitely Braque.
You nailed it.
His Rose period is my favorite followed by Blue.
I prefer Braque‘s cubism over Picassos because Braque’s shyt is so dynamic, engaging, and beautifully constructed.

I think Picasso wanted to play with the style without getting too close and got too loose for my liking.
