Look at Rainbow go! :o
Dashie is pretty sleek, though not as sleek as Rarity or Fluttershy. Her sleekness is apparent mostly in her legs and wings, as they need to be the most aerodynamic during flight. Her wings are smaller than Fluttershy's and Twilight's, but their size is actually pretty average for most pegasi, and their sleekness adds to her ability for extremely high speeds when flying. Rainbow is the second-smallest of the mane 6, but she's really only slightly smaller than the average. RD's face is the most angular of the mane 6.

That's all I've got for now. I'm not getting deep into personalities yet, I'm just focusing on appearance for these portraits. c:
