Obsidian Rain MLP

This is for ~obsidian-rain she asked me to make Obsidian Rain the pony. I tried to design it like her, and she got a look at it right before she got off, I hope the cutie mark color is more like what she was thinking now. I had it lighter before.
[link] if you want to see the concept sketches, there they are. The first two rows anyway. I progressively made it look closer to rain each sketch. I'm going to do another of Obsidian Rain though. She liked this pose a lot :3 but I like another pose more, and I'd feel disappointed in myself if I didn't make it a final piece. I'm getting better at drawing ponies although it's been...three days(?) since starting? three or four. There are things I don't like about this one, but I'm fairly happy with it :3

My head's been hurting this entire time :/ I need sleep. 4-6 hours just is not enough for me.
