I went to school for animation right out of high school. Like... literally, graduated high school on Friday, and had my first day of college on Monday. I went to school for five years, first focusing on traditional animation, and eventually shifting over to storyboarding.
Since I've been out of school I've been mostly doing freelance, primarily storyboards. I worked as an in-house cinematic artist for ~10 months doing animated cutscenes for a game, but outside of that I've been self-employed. I like my work because 1) it's storyboarding so I don't have to ink and colour anything :B and 2) jobs are quick and brief so I don't get burnt out on any one project.
Though to be honest, if I were thinking of art school today, I wouldn't go. I don't know your financial situation, or what kind of programs there are for artists in Spain, but in the U.S. private art school tuitions get higher every year to where I personally don't think it's a worthwhile investment. Especially when there are a lot of less-expensive alternatives like online mentorships.
Basically, student loans suck and if you can avoid being in debt forever, do that! A great thing about being an artist is you don't NEED a degree to find work. I went to school because I wanted to learn the skills faster, but I was under no impression that my BFA would get me jobs. Employers are more concerned with your skills first.
By the way, you have some nice artistic skills already! Keep on drawing and working on improving your skills, and don't fret too much about what kind of work you'll be doing. Chances are you'll find a niche over time that will interest you.
