Studies should never be sold as original art. I also think they should have not even showed the studies publicly. Something like that is only an exercise.As for fan art itself, I would never sell it though I sometimes make it. It's something people do but I don't have to do it.
I agree that studies should not be sold. I would even go as far as leaving studies out of your main gallery too, but that's me. XD

A lot of artists these days post things like WIP shots or rough sketches to engage more with their viewers so things like studies I believe would fall into that sort of category as well - it lets their viewers see how they go about broadening/expanding their current skill base with practice.
So I'm all for people sharing their studies on things like instagram/tumblr where it's just a casual environment as long as they give credit to the original they are using and are clear that it is indeed a study.
I could agree to this. It could be a good way to get viewers especially on sites like instagram and tumblr. Would you agree that the studies have no place in your main gallery on a site like Deviantart?

Everyone's stealing from someone. Whether it's art, writing, music, fashion, etc.
There's nothing that hasn't been stolen or appeared like it hasn't been. Regardless of whether it actually was or wasn't. Lots of artists say it's their inspiration that made them draw something. That can be true. But at the same time, someone else will say it was ripped off. While it could also have been ripped off because of greed/desperation/inspiration.
Most people who complain that someone else is stealing is usually someone who is stealing themselves. It's just their own cover. It's easier to lay blame on someone else, then to say it outright about their own selves. No one doesn't cheat from anyone.
The world wasn't created today or yesterday.
Plus, if they're not doing it for profit, no one should wretch about it.
Edit: (adds this) But as far as profit goes, everyone should go fight about how Hunger Games (The author denied the resemblance) is basically Battle Royale, that 50 Shades of Grey is actually Twilight...etc...
I guess this can be true, but I would press that this form of copying would be like making the Hunger Games with the same characters, setting, etc but change the color of everyone's hair and put in a purple filter XD
The difference between Hunger Games and Battle Royale would, for me, be more inspiration based than just copying. XD
