Really well done over all! I'd have to say I like this piece and how you managed to get the details in there, it looks good, real, and the expression on her face is well...Not enough, It could be a little more bashful perhaps? Embarrassment? Lust? Something along those lines. Only other thing that sorta caught my attention was her mane. I believe if we look at multiple pieces of art, we'll see that Luna has a two tone mane, one darker and one lighter.

Now, the background is one of the things that I love about this. It's detailed, looks nice, and reflects on her...well...the night, it reflects on her.

Last I really like how well the body looks and such.

Her Eyes...Although I like them, I don't...
I feel that they seem a little too glossy and reflective...It matches the style of the Artwork...yet it..seems off to me.

That's all I have to say on this piece, It's overall a good piece, a nice thing to look at, and that royal plot is incredible.

Vision I give it a 3 Looks good could use work.
Originality A 4 Plot shots have been done before, normally a 3, but it has it's own style
Technique a 5 because it's not seen often.
Lastly A 4 to Impact. It's nice, but not super impacting.
