Admittingly, when I was younger, I used to shamelessly trace art sometimes. I never shared them, though; I just did them for fun. Nowadays, though, for practice I try to free-hand drawings while looking at references. I don’t necessarily copy them, I just use a reference for my own pleasure/to improve my skill.
Example:
(The original image that I didn’t draw; perhaps I should find the name of the artist?)
(My version. I was inspired by the first drawing Because I’m gay for Lucina but didn’t necessarily trace it.)
I only ever trace if I have to.
