You did a fantastic job on the fine details, such as the lighting from the blue tendrils and window lights, as well as the grass that breaks up the horizon nicely with all the tiny little lines instead of a random tuft or thicker, uglier lines. I'm not entirely sure how to feel about the orange burst behind the tree, however. I like the contrast of the warm and cold tones, and the blend to purple is beautiful, but the tree itself kinda gets in the way, I feel. Personally I'd rather have it on a flat surface and serving as detail rather than a focal point for the warm glow, but that's really minor and personal. And yeah, obviously, the whale is fucking astounding.
