No but seriously... I think it's a hard question; on one side, I love seeing their own art so I can see their style etc., but on the other hand I love seeing how generous people are by having made something of this person's character.
I think overall I prefer seeing the art of others?? That way they're acknowledging other artists taking time out to make something of their character, I don't know...
I like seeing peoples characters on their page, weither they draw them themselves or someone else does. I usually always click gallery after I visit a profile anyway so it doesnt really matter if they have their own art there or not
I like seeing peoples charectors... Like when you see a certain charector ( for example Sanho) and you're like "yeah that's Powiibo's" but always give credit... I find it very annoying if you dont credit the people who made the picture
Being a non-artist, I prefer to fill my page with works that I comissioned from other people, as well as giving proper credit to those artists. So that, all who go to my page see the awesome works that others have done and the person I comissioned gains more watcher's views, etc.
I'd say their own art, I don't like going to someones page seeing all this great art then finding out it's just stuff they commissioned. Really a mix of both their own art and art of their chars is prob the best balance.
I prefer it when it's their own art so I can get a feel for their style without poking through their gallery, plus, it gets me interested. An art style can tell a lot about a person, so, meat-bags, draw it yourself!
