Actually, i don't really get like that, I go off and look up things myself
when i do a piece of art, i get an idea of where i've gone wrong and where i could do better so i'll go off and research that for next time or i'll keep it in mind and go off to learn something new XD i just never sit still long enough to dwell on any of my art.
But i always appreciate critisisms on my older works, especially if its something i didn't notice, because that then leads to a whole different tangent i could go off to research
Theres just too much stuff out there that gets my attention XD
