Those tree branches (?) in the center and left upper windows look funny, they are some sort of swooping up and down undulating shape I have not seen before.

The perspective of the trees outside the window is distorted, the branches are too large.
Compare with this picture of Reagan in the Oval Office. Look at the trees outside.
Re Trees outside Oval Office:
Yes, I think you’re right.
Also, look how bright and airy Reagan kept the Office. I miss him.
Not to mention it is February... it is WINTER... and the trees in Biden’s window are full summertime green.
