First of all, I will say that there was a huge arts program in the highschool I attended, so I was able to learn pretty much everything from oil painting to metal work. I was always pretty good at it all, so everyone was surprised when I did not choose to go to college for arts.
That's because personally I hated school. It didn't work for me, and I knew I didn't want to start associating art (something I loved) with homework and assignments and school in general (something I hated). I knew it would cease to be fun, and I would cease to want to learn it.
Working at my job has only cemented my dislike of college because for the better part of the year we are bombarded with students buying art supplies for their classes. Most of these students do not even seem willing to learn what the supplies are and what they are used for, and the rest of them who have at least a basic art knowledge complain that their teachers are very specific and not open to much creativity.
This is the most destructive thing I can think of when considering art school: Art is a creative medium. There are techniques and fundamentals you must learn, but other than that it's very open to possibilities. Many teachers seem too set on teaching the way THEY draw/paint/etc and dismissing any and all other methods.
I would recommend looking into classes outside of college - life drawing classes especially, if you are making comics with human characters. These can be fun and creative, and it's not a huge commitment like enrolling in college would be.
But, then again, I am biased.
