Oh most definitely. At some point I intend to draw Duskie, my Guild Wars 2 Sylvari character. Their color palette is inspired by the Silver Birch tree, my favorite species of tree ^^.
I'm rather fond of silver birches as well, especially their autumn coloring, when they remind me of Lothlorien. ^_^ It will be nice to meet your birchgirl.
Ooooh yes, they do look great in autumn! That said, I myself am partial to their deep green colored leaves in spring and summer, and fantasy variants where they have blue or purple leaves.
