Should I publish it?

Hello,

I am 15 years old and have been going to the gym for 5 months (occasionally, I often took long breaks).
Now I took a before and after picture and would upload it to TikTok. Unfortunately, the "before" picture is from April, meaning there are only two to three months between the before and after pictures. I was simply fatter at the beginning than in the April picture. But I'm not sure if that's embarrassing, since I still don't look good; you can just see the difference. By the way, I would also upload the pictures to TikTok as I've attached them here.

I know my form is still bad, and I don't want to brag in any way. I'm just interested in what people think, if you can say that.

My main problem is the fear that my friends or schoolmates will make fun of me if it really isn't good. I'm not good at judging that, hence this question. By the way, I was always the shorter, fatter boy/I still am.
