This is my attempt to draw a human Applejack. I did my best to keep her true to the pony character;freckles,frowns and all. Even the nose is a bit upturned.  
To be honest in the beginning I thought she looked a bit ugly, but she turned out ok.  
I initially based this drawing off a small boy with freckles-it took some serious effort to make her look feminine. I don’t think I succeeded completely.  
Overall she looks a bit manish, like the character from king of the hill, but I think I succeeded in pinning down the angry pony look. P.S Look forward to a beautiful Rarity next.
