Lovely photo - and it reminds me of a dear friend I have lost.
My friend and I adopted a cat "together". She kept custody - I got to love on him when I would visit her. Unfortunately, he got out and hasn't come back. He looks just like your cat. And we had named him Rocky.
This is my own personal voting scale. It's merely an huble opinion, based on whatever limited photography knowledge I have. You have all right to agree/disagree with me.
I don't care for the visible junk in the lower left corner there but I do like the slightly upwards angle on the cat. Little bit more light might've been good too.
I think cats are magnetically attracted to windows ;-) Like the light coming in on him, but I would simplify the scene by covering up, removing or cropping out the clutter by the window.
