The idea is to take another picture say in 6 months time and compare them. If your hairline has receded more than the first picture you might be balding. If it is the same then your mind can be at rest that nothing has changed.
It looks fine. There’s a process called hairline maturiation. That happens because your baby hairs die out and your adult hairline starts showing. Like the guys here said keep an eye on it. I wouldn’t be too worried if I were you.
