Lux, shut up and listen for a second, would ya?
PRACTICE MAKES MORE PRACTICE.
First rule of drawing. You'll NEVER be perfect, no matter how much you try.
The fact that you're GIVING UP because you tried to COPY your reference and couldn't, instead of trying a few times to see if you could get it right, is sad. You say you want to be an okay artist, but you're not even willing to put as much effort into practicing as you are for complaining.
All I'm seeing is "QQ, PITY ME, I CAN'T DRAW EVEN THOUGH I'VE BARELY TRIED". Want to get better? FUCKING TRY.
