I liked the plaid one, but you have to make sure it's big enough for all the stuff (cause they looked small) and that the bottom won't fall out. I had a backpack like that and in the middle of the hall the bottom just ripped and all my stuff fell out! God, it was embarrising....
Personally I think the green one, and if something gets on the pink one it would look terrible.
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.
