That doesn't look off to me. There is a dark spot in the first frame -- it's just masked by the much larger shadow going across the whole wing.
It seems fake to me, but I have yet to be convinced there's CGI. If it were CGI, within 2-3 hours someone will post a statistical analysis of the images. That would be extremely obvious, whereas most people in this thread are pointing out things that are ambiguous.
I mean they if they got the trees, the shadows, and the grass right, then I have a hard time believing they forgot to remove a dot somewhere on the wing. Those aren't the kinds of mistakes you would expect if someone was trying to match CGI to real footage.
