As the title says, art might be my passion. I do really good in reality! I even drew a map of Lareli, a city of my own creation. I would remake it on Paint but I'm not going to yet.

No, really if art is your passion, my best tip is DON'T practice just to practice. Practice by taking requests and allowing other people to enjoy your art with you! The only reason people I didn't know well liked me is because I drew pretty good art and did requests! Well, thats my tip-thingy.
Realistic or anime/cartoon
It's excellent that you found your passion, or might have at least. I'm very happy for you.
As long as you believe it's your calling... chase it, and let no doubt hold you back. If you find yourself drawn (pun) to making map after map, then you might be specifically passionate about the concept of world building. You may want to look into that.
