keep practicing! i know the feeling of looking at artwork and feeling degraded by it, but if you look at it as inspiration rather than a let down, you can motivate yourself to try to achieve being at the certain skill level you want. all it takes is determination and lots of practice. ^^
i have a lot of practice since i started getting into art at a very young age. i tend to draw even small things everyday, even little sketches on my homework in class. it’s also something that sort of runs in the family, although there’s no telling if skill is something inherited lol (my mom went to art school and my sister, who’s only a couple years older than me, is also very into art and planning to go into that sort of career. it really is something passed around in my household lol)
