Help with getting more attractive?

I am a 15 year old male who is 6 ft tall and weighs 161 lbs at 15% body fat. I will be finishing up my freshman year this week and getting ready for summer. I am hoping by next school I come in a lot more physically attractive. I don't look fat right now, I just have some athletic chub. I don't have a real defined jaw line and I don't have my adams apple showing very much. This year i didn't really want any relationships, and no girls liked me over the year anyway. Since sophmore year I am only taking 1 AP course, I think it would be nice to find a special someone. I might be attractive already, idk, but I would like to be able to go into next year looking really good. I would like some tips on what would help my attractiveness. I am open to any ideas. I know that confidence, humor, charisma, and likibility make a man attractive, but I am looking for things like 6 pack and muscles, or thin and lanky, or lean ripped where it doesn't look like you work out but you have muscle lines that aren't very large. I am really looking forward to working my *** off to make myself as attractive as possible. Thanks, and you can answer this with what ever you all find attractive, show it to some friends, I want to get a lot of answers for this
