Firstly, I don't think your OC's mane is "flat," or her tail. Just because it's not stiff and bouncy-looking doesn't make it any less accurate; I'm not even sure where that critique is coming from.
I find the color pattern quite appealing, though the purple eyes clash a *little* bit. The "no eyelashes" thing is complete crap; based on her pose and where her mane is, you can't see her eyelashes.
The overall head shape seems a little bit too high up, almost more like a filly's head than a mare's, making the neck seem a bit too long. The head also shouldn't be completely separated from the neck by the line. Ears likewise seem just a little bit too small for the rest of the body's proportions. The rest of it seems great to me.
Seeing as you originally created this thread to ask for a name, not to have your picture ripped apart by us ruthless /oat/ers, I quite liked the "Asteroid" suggestion. Clear Skies seems a little bit too cheesy for my taste. I can type you up a little backstory or something if you'd like to try to develop some before you decide on a permanent name.
