Remele is a talented artist, but steals art from others without regard to copyright laws. According to her, she takes other artists' art and makes it better. She does not give credit to the original artist at all, instead claiming the art as her own and making quite a tidy sum off of it. When confronted with accusations of art thievery, Remele will become slightly defensive and vehemently insist that her works are all original and completely unrelated to the originals. 

She may also have a twisted sense of justice, since she believes that the best way to get back at the artists trying to undermine her is to steal their art from the museum.

Remele is shown to be quite responsive to praise and positive comments, and becomes visibly delighted when someone compliments her on her work. Should anyone give her negative reviews, however, she will call said person a plebian and have them shown the door unceremoniously. This might imply that she has a bit of trouble taking criticism, constructive or otherwise. 

When a purpleblood accosts the player, Remele is quick to abandon the player to fend for themselves. This might show that she only cares about her wellbeing, and would ditch her accomplice the moment things take a turn for the worse.

Remele has a lot of self-confidence, and has no trouble talking her way out of situations due to the level of cofidence she projects. She states that she has an easy time trusting herself not to fail when it counts, and has a rather indifferent attitude to the dangers in life.

 She does not seem to care about formal mannerisms, however, as she was seen to swear quite a bit when speaking with the player. 

So basically, just imagine her as one of those 8 year old kids on DeviantArt that traces.
