The shape of the cave looks like wings, very cool concept. And the red glow really does give it that sort of "down to business" or "doing everything for survival" type feeling. I have to say that the back of the caves, the kind of misty light blue part looks kind of empty. I would suggest putting some enemies or the Sun Queen Himiko (that's her name right) back there; or a gold glow, like the innocence of the the light of the Sun because I understand that the blue if the innocence and the red is the lost. Overall, I really like this picture. I'm browsing through all the entries to this contest and lots are purely amazing, I wish there were 100 spots for winners, not just 3.
(PS, this was meant to just be contructive feedback, if you choose to ignore it, it's totally fine. Good luck in your next contest if you enter one!)
Thanks for your comments, I probably won't be working more on this pic, but it's always nice to get feedback. I'm glad you spotted the 'wings', The Sun Queen didn't come into my thoughts while I was painting this as I restricted myself to only using the reference supplied, which to be honest gave me very little to work with other than the figure. I'm quite pleased that the Final winner of the competition was the picture that I personally would have chosen, so no hard feelings there Thanks again
