Dude it's really not that bad lol. I'm laughing because it's a regular picture and you're overthinking for sure.
I assure you I'm not. I never really thought I had short arms until a couple girlfriends pointed that out.
I mean, I did notice in my 20s that whenever I bought shirts, I had to have a tailor shorten them, but I was like "Meh, who cares, shirts are made in a factory based on some template". But then I met these women who pointed out that my arms do look short. Maybe that picture isn't the best to illustrate it, and I'm not going to debate the topic anyway. Suffice to say that some people do notice, I don't care enough to have another surgery, and my wingspan is only 5'2", so even at my original height, it was 3" shorter.
