Love the flag look but it does not match up well with pastel. Red whit and blue needs to be all red white and blue
I think the flag is great idea, but I think it's too hard to read to copy with the flag underneath it. I would also go a darker color for the print on the back cover to make it stand out more. Right now it's a little hard to read.
Just my opinion, but I used to do graphic work for my job at the school district. :)
