Should I follow my dreams of a Modeling Career?

Le

I really love photography, taking pictures of others and myself. I would consider myself a pretty attractive person and I’m interested in trying to start doing some small modeling for local companies. I’m kind of ashamed to talk to my mom about it because I’m not exactly skinny or what most models look like and I don’t think I’ll be accepted by any agency’s but I believe it’s worth a try. Anyways, can anyone please give me some advice about telling my mom, making a modeling profile and looking for good agencies?

By the way, I am 13.

These are a few sample images, if I do end up making a portfolio one of my relatives is a photographer and I might ask to get professional pictures done instead of my badly taken selfies in my window 😂. Thank you to anyone who can help!
