Lunar Protector

Don´t really have much time draw, at the moment, but i found some spare hours over the weekend.
Kind of an armor design, but i added a background to it.
The idea was to show Luna in an alternative, non-evil-looking armor.
I cropped it slightly, since i thought that the ratios weren´t perfect.Here is the uncropped version : Itsahorsefinal1

I still suck at basic composition, i think i am getting the grip of this color scheme, though.
critique is, as always, appreciated
