I did something similar when I was that age (I had ATR tattooed onto my shoulder) Only to get it covered up a few years later. Brandings are a lot trickier to care for to get the desired result (which is raised scarring) and I would advise that next time just wait it out and get it done professionally. It will be worth it.
These were my brandings when they were just done.
(The artist posts all of his work on BME so it was the easiest place to get the picture)
