I tried to find another picture, but I couldn't find the right one, so I changed the color of the background now. The character's clothes are purple, so I unified the character and background into one color! And I added some Gaussian Blur to the flying leaves.
It's not easy to improve completeness. There are many times when I think I'm done, but I'm not at all, but this difference is making me suffer. 。゚(゚´ω`゚)゚。
