Dayum, this is so pretty~ *_*
I love the warm autumn colors, they're quite different from your general style of predominantly cool colors with a touch of warm ones for contrast. This just screams warm enchanted forest to me and I especially like his pose - he seems troubled or annoyed and it's in such a clash with the serene and warm background, lol. That little pool/well behind him is especially adorable and pretty.
And gwah, love your videos, too, they clearly show how much work goes into everything, almost like a speed painting tut I saw once on dA. Makes me wish I could try it out but alas, my smoothing, smudging OCD always rears its butt and demands perfection of colors and shades, lol.
Great work, Tsu, can't wait to see and read more about the story behind all this. :3
