Ohhh, looking beautiful so far. Love that background.

Ethereal. Lovely.

i really really like the background . from the thumbnail, this looks really impressive.
my only suggestion would be to put more hair on the mane; cover up the back of the neck a little bit more.

unless of course, you used a reference and thats how it looks then nvm, i'll shut-up :X

lol.. no ref.. but I shall try your suggestion none the less...
thanks!
:P
