I love Hiyori she's funny and can control people xoxoxoox

I like this wall, mainly because of the character's facial expression.
Lol. Other than that, the shading differs in each image groups. The backdrop's (sky) shading is very detailed while the buildings have a little less but debatable shading quality. The character has a completely different style. It's mainly fine edge shading, while the other images have gradient shades. Try and mix the shading a little better together.

The tint of the shading is also important. The shading in this instance would have a yellowish/orangish tint, since that is the color of the light source.

Otherwise good composition, some text might have worked to explain the situation, tell the character's name, or even work as a punch line. But good job.
