my parents used to nag me even when I painted a lot (which come on, everyone considers a serious form of art, right?). It's a rule in my household: no painting in the house. I used to just lock the door to my room and sit kinda behind my bed and paint, though (it makes sense with how my room was set up). Maybe my family's odd, though?
but I'm not an art major either... so that may be why my parents/family want me to focus less on comics and art in general.
I think a balance of art and comics are just as important. Taking up art improves skills and creativity. But taking up comics helps inspire free expression and inspiration.
