I would say look into surgery for the skin if you want.

Beyond that... what are your goals? What do you want? Because you are currently hot enough to be attractive to most people. You could be buffer or more cut, but if your concern is attractiveness, you have hit a point of diminishing returns with your body, and would be better served focusing on things like dressing well or becoming a good conversationalist.

If your goal is health - just keep doing what you are doing. Good job. Don't overthink it.

If you just want a goal, my recommendation would be to get some kind of hobby that allows you to express your newfound athleticism in a fun way - martial arts, gymnastics/acrobatics, team sports, etc.

And if you are really committed to having the best looking body you possibly can - then it is time to stop pretending and become a bodybuilder. Sign up for a bodybuilding gym, make bodybuilding friends, hire a bodybuilding coach. Asking the internet for advice won't take you nearly as far as really committing in real life
