I actually started with this character, but then changed it completely while keeping the same painting as a color reference. I think this character fits with the spirit of the painting a bit more, but wanted to give the character a bit more attitude while using some of the same elements.
I kept the pointy shoulder piece and the staff. The painting has a feeling of exploding upwards, so tried to keep that up a bit with the pants and the helmet. And then I thought it might be funny if she was a little self-conscious about the fantastic outfit she was wearing and maybe not too happy about being an elemental guardian.
