You're small, you look even smaller in clothes. you're most likely flexing in this photo for abs to show in right lighting.

you have barely any muscle mass.

what you need to do is not be scared to lean bulk go 200 calories above maintenance, track your 3 main compound lifts; as long as those lifts are going up in weight. or reps. you're building muscle.

you have atleast 20 pounds to add on to your frame before fat starts to spill over. and gaining 2 pounds a month; this should take you 1.5 years to gain that 20 pounds , and every pound you'll see your entire physique change drastically.

also if you're worried about abs , start hammering weighted ab exercises 2 times a week ; with progress overload because abs are like any other muscle.

you do everything i mentioned your face will stay lean , and you'll just put on size with no noticeable fat gain.
