One of my dream since I was a child is to be an artist of mtg...

Coz I really inspired when I see a trading card so I ask myself when
Can I make my own card... mmmhh

I started to discover my talent when I was in grade 2 .Every night I can't help myself to draw my fantasy creature in my notebook.
I also remember that I've done 2 notebooks with full of drawing..
What is the best course should I take in college,?
