I love Jennifer Lawrence in the movies, however I read the books first and I feel like they are almost 2 separate entities. When I read the books this is what I picture, not the movie versions. My Peeta, Gale, and Haymitch all look very different from their movie counterparts. Prim, Effie, and Rue were all spot on for me though.
You should make a deck of cards out of the hunger games characters. All together you could have a total of 89/54 cards. If you do want to do this idea, I have a decent idea as I have designed decks like this before.
Also, everything about Katniss seems right except for her size. Katniss is described as: "...small in stature and thin for her age...", and she was "...one of the smallest tributes in her games..." other than that, skin color and wounds, it is very accurate.
