Saertheron of the Wilted Lily - Souls-Like Boss Challenge

A few friends and I thought about making a challenge to design a boss that would fit the Dark Souls or Souls-like world, so I thought it'd be a good opportunity to try and learn some new things like painting different materials, mainly metals, wood and cloth.
Considering how Souls-like bosses often have this sort of "Irony" factor about them as far as I've noticed, such as in the way they may be corrupted by something, I thought that maybe Saertheron could have been some kind of knight or protector to some kingdom that had a lily as the symbol, after the fall of said kingdom, perhaps the knight went mad, and of course some sort of dark magic twisted him to the way he is, with the wilting lily now literally at his core.
Either way, I had a lot of fun with this one, and it's by far the most amount of time I've spent on one single image. It was my first time properly "painting" instead of the more cartoony drawing, and I will say it was a joy to try out.
