//A headcanon? Hm, Ariamis, while an exquisite painter, is no good at sculpting.
// Well, well I was thinking about that a time ago! By the several statues in Anor Londo, especially the statues of Ornstein and Smough.
I am not an expert, but I know that to draw something and look good, you need to understand how that something works, So to start an illustration with something you do not normally draw or have never done, you need to practice before.
So, Yes, you’re right, I do not think that the sculpture is for Ariamis, maybe he can sculpt something decent if he tries, knowing how, for example, the human face works, however, I do not think he like the materials neither xDIf he has something to do with sculptures, maybe is making references in paper, You can imagine Smough posing for a sculptor?
