Artists, especially young artists: do not feel bad about wanting to create beauty with your art. If what you want to draw is beautiful people, go and do it, and do it the best you can, without reservations. There is a kind of ugliness-elitism that seems to come from art schools and similar institutions that says that beautiful art (especially beautiful representational art) is shallow, and that valuable, interesting art is defined by ugliness. I’m here to say that it is much, much easier to make something bad than it is to make something good.
The worst case of this is young female artists who want to draw pretty girls. These people get shit on by adults for drawing this stuff. Girls who want to draw magical girls, shoujo girls, or bishounen, who want to draw people that they find beautiful. Fuck those adults. That ugliness-elitism is a way for self-defined arbiters of taste - whether this is the critics, the examiners at art school, or your art teacher at school - to get to decide in advance what is valuable and what isn’t, instead of allowing the art to speak for itself.
Representational art is valuable. Beauty is valuable. If it’s what you want to do, then go forth and work your ass off creating something you find uplifting and lovely to look at. It will take a lot of hard work, trust me. It is easier to make something bad than it is to make something good. That work is worthwhile and don’t let anyone tell you it’s a waste of your time.
