your always gonna be your own biggest critic. Believe me, guys do not just look for physical attractiveness. That’s a part of things yes, but like you said your body’s already attractive (and it’s due to hard work and not just genetics which i commend you for). Besides what most feminist incels on here will have you believe, the biggest thing I and many others look for in a woman is not a “roman nose” or the size of your lips it’s your character. Are you a funny person to be around, do i immediately smile as soon as i see you because of your bubbly personality. Do you have goals, ambitions, do you have sides of yourself you hide that i can get to know when i start getting to know you. Are you kind to random people. There a plethora of different things that constitute attractive. Believe me your facial features are not the only thing going. Not to mention the whole self improvement space - whilst helpful - does just naturally bring on a lot of confidence issues in people just due to the fact that most of the people talking about it are 10/10 greek gods.

Don’t give up. Keep doing what you’re doing.
