The trick is to supplement ateliers with online schools like CGMA for your specific niches. The problem with art schools is that they don't always have a great foundation in art skills and you see a lot of people graduate who still don't have professional skills because they're for profit first and foremost.
I feel like you're another me. Weird.
Wanted to get a master degree in Illustration. After much research realized it wasn't worth it.
You need to write down the positives and negatives of going to art school and not going to art school.
Positives:
Bachelors degree and self fulfillment.
Places like Art Center have resources for students after graduations due to connections. Many famous artists in the field you're interested in will give lectures.
Sense of community and connection.
The easy ability to focus on your niche.
Negatives:
Most art jobs do not care about degrees, they care about skills. The question is "can you do the job?" And they won't even ask for your degree once.
Art schools are for profit generally and are an easy way to get into debt. Do not take this lightly because for profit means they may value that over your art skills.
Many art schools place emphasis on abstract concepts like conceptualization and individualization than art fundamentals. So you'll have artists who have been trained to try to do art creatively - after all, after the modern art movement everything is art, who is to say your art is bad or not professional level? - rather than with strong fundamentals. The problem because an artist who has ideas but without the skills to put them down to paper.
Art schools aren't always as well rounded in art education.
It's common for an art school graduate to have 100k in debt. That is not worth art education.
It's easy to want to feel like you need that bachelor degree, and I can't blame you. But do not rush this.
I joined Art Camp and did that. I'm doing Watts to get fundamentals in anatomy now. I'm hoping to do digital painting classes CGMA 2d next year. Watts online classes are good but if you want a quick crash course I suggest Art Camp instead.
