>it feels different from the cool art of Aya or the Hifuus.
True. Aya's art, when it is background/environment driven, tends to have action or turn very picturesque, sometimes with a darker mood due to her being a youkai. There are often other people in the background, angles from bird's-eye view are very common for more than one obvious reason, if the scenery happens to be oppressive, she still looks as if in her element.
Sanae's pictures are more toned down, neither as bristling with energy nor with dangerous undercurrent, more contemplative, but still hopefully optimistic. You can tell this is a girl enjoying the scenery she fits in, on some psychological level. This optimism full of tender hope pushes towards things that are alive but calm, like mountains, trees, bodies of water, composing well with green hair and blue skirt, incidentally.
On this level it contrasts with Hifuu, who are usually either in liminal, decayed environment, or modern, fast-paced city landscape that is not really alive.
