It’s Juno! I’ve been trying to draw her forever now, but it would never come out right. But I finally did it! I really love how this image came out, her anatomy is kinda more realistic than my usual cartoony stuff.  
(still no cutiemark cause I haven’t figure it out yet), she’s supposed to be like a tween, but I’m pretty sure she looks older here so… yeh…
 
Small bio for those who don’t know this cutie cause I’ve literally only drawn her once before on my DA:
 
Princess Juno is the Daughter of Princess Luna, and a bat pony (no design yet). She works with her mother to protect the dreams of ponies across Equestria, except Juno focuses on the dreams of foals and young ponies. She fights off Nightmares and helps foals with the problems they are facing so they can get a peaceful night’s slumber.  
Her freckles on her face glow in the dark, and although she does have a somewhat scary appearance what with her fangs bat-like wings, she uses this to her advantage and tells the kids that she has them so she can scare any bad monsters away. Kids are usually distracted by her hair long enough to forget the fangs and wings or become used to them.
