I always wanted to see a huge team vs each other and see who would win.. like, Marissa, Mokou, Eirin, Flan, Meiling, Yukari vs Sakuya, Remi, Reimu, Alice, Kaguya, and ect. Lol.. XD But probably whatever side has Yukari would win. XD
I'm not saying anything more than just that: "Influence". Quite possibly, you have both been influenced by the same (older) reference, each yielding a similar, yet entirely original (and very good indeed) resulting composition. Can't wait to see the colored version too.
