She has almost all vampire pony traits except for the eye-color.
Wings being same color as the body, ears a bit too open, the eye-pupils look normal (And not a small straight line, like a dragon), etc.
Bat ponies ears are same as any pony else except for the tip of the ear. They have those dragon-like pupils. Their wings are normally dark colors or colors matching their hair and mane; and always in TWO colors.
Technically, you drew a vampire pony with purple eyes instead of normal red eyes.
