I have been putting my PS skills to test, yes I know, I'm not very good at that, but any ways, I tried to removed some cipres twigs in front of the sparrow's bill.

I like the singing pose and details and would give it a bit more room at the left. There is one OOF branch behind the bird's head that doesn't seem to belong to anything. You could try to clone this one out, too.
Ok Axel, I know is not the best job but this is what I could do, I don't know how to add canvas so, it will have to wait. Please let me know your thoughts.
