It really looks like Epona from TP.
Oh my gosh, this is amazing! Seriously one of the best Link cosplays I've ever seen!
The blurred background and the lighting adds a really nice effect. If gives the picture an adventurous, fantasy-like feel to it, which is perfect for the character! Your costume, especially the sword and shield, look amazing!
I have to know, what did you use for the chainmail? It looks awesome, too!
