abdomen muscle is too narrow, should be wider. Pectoralis is too low, lift them up. triceps should be more smooth. The wide thing at the bottom(supposedly start of pelvis) should be lower too.
Can't you look at yourself? I mean you should know this if you are in high school or beyond.
I am in 10th grade, sophomore in high school, but if you don't take me serious, I'll make you.
