I can never gather the confidence to show any of my art to anyone?

"I draw usually from imagination"

Ah... It's always refreshing to read that.

When I studied art I found it really strange how many students would rely on copying (whether from life or other art) to create images.

Yes, it's normal to be self conscious about your artwork. I used to be very embarrassed - somehow it was made worse by the fact that people kept pointing out how good at art I was. I had no idea how to take a compliment, and the praise didn't actually make me feel good, just anxious.

There's nothing wrong with keeping your art to yourself. If it's a private hobby, then don't worry about it. You're drawing FOR YOU, not anyone else.

so do some landscapes and some inoffensive kinda stuff that yall can show round. itll be a challenge to git yall outta yalls usual comfort zone and if yall gots any talent itll come out good. keep the weird shit to yallself.

if yalls an artist peoples gonna expect yall to be weird anyways. yall might get some satisfaction throwin peoples off by a lookin all weird but a paintin something that theyall think beautiful. it might even git yall noticed better

if yall git established the weird stuff can come out later

Have you considered making an account on deviant art? Or some website that allows one to show their creations anonymously? It's one step towards boosting your confidence.

Although, be aware that your artwork may appear in other places on the internet. So, choose carefully on what you feel okay with sharing and create a certain signature if you want credit.

how old are you may I ask?
I was self conscious about my art when I was younger because in my teenage years it was a very judgemental and stereotypical environment. With maturity and the company of maturity it becomes a lot easier to exhibit and for the artworks to be embraced properly and interpreted subjectively.

It's normal to be self-conscious. The thing is, is that art is so subjective, but there is a standard for professional work. I understand this because I also do art. You say you aren't professional so you don't have to worry about that. I get the feeling, however, that you are comparing yourself to professional artists, and noticing a difference in skill. You shouldn't be because even those who do art for a living, look at their own work and don't like all of it.

There's a theory that as an artist paints they improve and so by the time they're done with a painting, they've improved past the point of what they just completed. That's why artists are never happy with their finished product, because they're beyond the point of when they started.

Don't stop making art. Show your work to others, maybe a close friend to get some feedback. Most people who don't do art aren't critical and will be impressed because it's better than what they could do.
