aacckk!! at my age.....not so sharp anymore
but anyhow, see if you can find the 3 differences between these 2 photos.
at first I could only find 1 thing, I must've stared at these stupid pics for 5 minutes or so until I finally gave up in disgust.
but once I was shown where all 3 were it was so much easier to spot them, but until then I was thinking "oh man, either my eyes totally suck or this is total bullshit!"
spoiler:
1 of the things is really subtle, I can only see it if I get close enough to see with my peripheral vision or something (kinda reminds of those pics that you can only see if you unfocus your eyes slightly)
but the other 2 things are pretty darn obvious once you know where they are.
good luck!!
