This is why she always had her mane over the side of her face, it's to hide all the scales and dragon eye. She is rather self conscious about they way it looks and how the always had that mean look to it even when she's happy.

Everypony has a side of themselves they don't want to show the world, some just have it on the surface.

the scales where all hand drawn by me, the original art is by Shadowfoxsilver on tumblr, drawn for me just reinked and coloured by me.
I really suck at drawing donkey ears and I just realized I forgot to colour the muzzle. will have to fix that later.
