This is one of my DND characters that I originally played with however, I wanted to have a better visual so I drew it myself.
My updated version.
I kept the base color but added a purple secondary color to the armor, giving it more variation. I also changed the cloak color to blue with a gold trim to give it more of an elegant sorcerer look and feel.
The original version that I wasn't happy with. I felt there wasn't enough variation in color so it felt very uninteresting. I also felt the colors were too similar to some popular characters so I decided to change them around.
