Holy poop you know a lot. I actually have my Kagamine Rin shirt on now. XD She is definitely my favorite :) Miku is ok but I think she's kind of overplayed.
Other than that my favorite would be Lily, Megurine Luka, and various touhou artists.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
