I would have opted for wider aperture :
# To get more light and thus a faster speed;
# Isolate the subject from the background.
In addition, you get the best resolution of a lens when you stop down 2 stops which would be f/2.8 for your 85mm.
So, I think you could blur more the brick whole, which is a little disturbing.
That said, your subject looks sharp, and the IBIS function probably helped a lot !
I guess you are happy with your 85mm ?
