Atop the Lighthouse (I need some good comments guys!!)

     So, after not having looked at it for a long time, I've finally found time to start working on this image of the scene from the Lighthouse of Alexandria again. It's still extremely rough but, I've got a pretty good idea of where I want to take it from here but I would really like some input from some of my fellow artists. I don't request comments much but I am now. Please feel free to comment to your hearts content with regards to how I might be able to improve the image (without starting over) :)

There are a few areas that I will point out that I would like help with. But feel free to make any other comments:
     I know that there are a lot of you out there that have a better knowledge of horse anatomy than I do. So those of you horse lovers, please feel free to make any comments with regards to the anatomy, expression, and even the wings on the horse. I'm not 100% sold on them myself yet.
     I'm going to rework the gesture and pose of the characters. So don't focus on that as much at the moment.
     One thing that I would like some input on is the lighting in the image. There is obviously going to be a large amount of light coming from the various flames on the harbor. But I also want a nice balance between that and the moonlight. And I'm not quite sure how do achieve that yet.

Anyway, feel free to make any other comments. Also those of you who feel like you have enough free time to do any sort of paint-overs or anything like that.. feel free to slap some colors on there and email it to me at stephen@stephensitton.com

Thanks guys!
