I've never noticed that. In fact, what fucks me up sometimes is how many new artists appear out of nowhere with amazing art. It makes me feel bad that one of those artists was never me. I have always wanted to draw like they do. I got some halfway decent starts too.
I used to color an artist that I personaly knew's art. I got pretty decent at it but I don't do it anymore. One time I actually tried drawing one time and I was in complete ecstasy that what I was drawing didn't suck at all and it was my very first time doing it. I made the mistake of posting it in /i/ and then I got really fucking embarrassed and deleted it but not after a really good artist (Subtank) redrew what I did and made it look very good.
Since then I've just always made the excuse that I have no motivation or time to do it which is true. Someday.
