hello ana!
your horse isnt really chestnut, its kind of a faded brown. remember chestnut is red, most horses that are chestnut are just called red to avoid confusion (bc i personally say chestnut but one of our borders calls it sorrel, same color, different names)
also remember that a horses nose is only pink when one of the following is in play:
-the horse has a marking that overlaps its nose
-the horse is albino, pearlino, smokey cream, or creamello
because your horse has none, the nose really needs to be gray, and it needs to look like
