Avamire the Unicorn

This is one of many unicorns I've tried to draw. I've dubbed it 'Avamire' for a cool location that I found in a book about unicorns. I'm a bit too old for this but they are really fun to draw and shade, while not being as common as a horse. This unicorn happens to be white, which is why only the necessary shading is done to make it look as realistic as possible. I'm welcome to any tips or advice; please comment if you have something to say.
