a nice happy picture of little Flutter with her mommy, Fluttershy. They look almost alike, dont they~
 
I wanted to show that time has passed and that Fluttershy look a bit older, so her hair is a bit grey like that, kinda showing shes much older than from how we all see her. Some key things about the differences between Flutter and Fluttershy is the eyes. Fluttershys eyes are a beautiful blue (i think, ill change it if im wrong) and Flutters are a deep purple, probably from her fathers side. This is the main one out of all the differences, the second one being the mane style.  
Fluttershy (as a filly) her mane would cover her eye no matter what, and it looked very thick and smooth (thus the lines in her mane and tail).
 
Flutters mane is a bit more uumm messy, and not as neat as her mothers, but she does style her hair whenever she tries to. Her tail is also something to notice, since its barley there. She doesnt like her tail wonder why
 
But yeah, all questions are now being directed to Fluttershy until my next payday at work.
