In this image, we can see many elements at play (mild pun). We can see the absolute dedication fluttershy feels towards her friends and her ceaseless desire to put others at ease, even if it means going well out of her comfort zone. Whilst pinkie's attention is fully consumed in how willing her friend is to cheer her up that she is ignoring what looks like a rather unpleasant sneeze festival. I do believe that this image is a very accurate representation of the characters and you have done a wonderful job of expressing them as who they are.
