Ahh, thank you! A very good (or bad) example of this would be in the JTHM comic fandom and a few others. Literally 85%-90% of the "fanart" posted up here are direct copies of pictures of the comic, only in a lesser quality. I can see why people can start off with tracing a character or heavily referencing a picture, as it can help to understand how everything is put together.
However, you need to be able to break away from this method of "learning"
In addition, they have the odd boldness to post it up onto this site.
Why should you be proud of something you traced or recreated?
Why would you want to show everyone a crapper version of it that only makes you look bad?
Worst of all, so many of the people do it that many don't see it as wrong.
I'm more baffled then anything.
