Looks nice and clean, the theme is pretty consistent throughout. Overall though it looks a bit bland. You could use a little bit more contrast in the elements. Stuff that the player reads should stand out more. In example in the score result screen the numbers should either have a darker outer shadow or the background itself should be darker with the numbers having a subtle glow to accent it. Also the cursor blends in with the rest of the elements and should stand out a bit more, you could pick a color similar to the sword of hisou. Tenshi has a variety of colors to pick from since she has rainbow colors, the peaches, scarlet eyes, her sword and you seem to focus a lot on the blue hair and white dress piece. I like how you used rocks throughout as elements, though it would work better if tenshi was catching peaches instead of rocks.
