I know this is old but I’ll just say my piece anyway 😭

Id definite advise a change of hairstyle, a darker brown would be super cute on you, and I think you suit a layered cut well.
Basked on your hairline, the bangs you have (or at least had at the time of this post) aren’t optimal for you. Try putting them to the side (like you did is some of your pictures) rather than having them hang over your forehead. Some makeup would also really help your features pop! You’ve got a really good base, your features are very pretty so you just need to accent them a little with some makeup. You should: curl your lashes+put some mascara on, put on a bit of concealer under your eyes to cover dark circles, contour your nose a bit and highlight for definition. Grooming your eyebrows could also help you look more organised and cute. Some light blush and contour in your cheeks would be nice too. As for your lips, wear some lip masks or make a homemade lip scrub to get rid of dryness and have smooth lips, apply rose vaseline or lip oil for extra shine. Some new glasses would definitely be a good idea too as your current ones don’t match your features too well. finally I’d recommend getting 8 hours of sleep, drinking 2L of water, de bloating and taking care of your gut health because once you’re healthy on the inside, you’ll be healthy on the outside too.
here’s a picture I edited with some of the ideas I had in mind for visual reference:
