"... one of the most important Wolfriders, which has been the least drawn ..."
Wonders who this would be ... a chief? Tanner? Goodtree? Two-Spear? Or just a tribemate I cannot think about now? Looking forward to see your artwork!
About Goldilocks' new clothes ... I actuall think brown suits her- it goes well with her remarkable hair and dims it down a bit. Bright, dominant colors in the outfit might make her gaudy. On the other hand - going with all browns will make her Joyleaf's lookalike.
I was thinking of basic brown - with a highlighting color. A fair pink (rose?) came in mind - like those Japanese cherry blossoms. Or a fair blue - matching the Summer sky.
Sungold- Skyblue - Earthbrown ... a color scheme I could imagine for her.
