Wow, what a lady! It turned out interesting!

Vera Petri, Thank you, Vera! The girl was really little, maybe eight years old. But what a look!

I liked it, very good!
In my opinion, a slightly lower shooting angle would have looked even better.
Good luck, Aida!

A good angle for a flat background. I might have removed the spot behind the head, but the portrait is very good, as is the model.

Nikolay Semenov, I agree about the stain. But.... is the background at a good angle??? .... I don't get it!

Nikolay Semenov, I agree about the stain. But.... is the background angle good??? .... I don't get it! Aida, I'll explain: take a lower angle, and the luxurious background will disappear; take a higher angle, and the front edge of the hat will obscure the pretty face.

Nikolay Semenov, I understand. Thank you!

Nikolay Semenov, Got it. Thank you!

And one more thing: about an unknown Renoir canvas: https://transfiles.ru/imafm

And the stain can be easily removed in Photoshop, with a stamp, and not only in Photoshop... there are plenty of editors where you can do this!! I really liked the portrait!!
