wow! This new style is great! However, there are a few tiny little pointers that I would like to say, just to help you improve! I dont mean that its bad - not at all, just a few areas that could be improved slightly.

This is already beautiful - your anatomy and colouring is absolutely gorgeous - I cant say I would change too much there - only perhaps that her front-right leg looks a little... awkward? Maybe shift it forwards, just slightly - also, if you look sideways you can see that it is marginally longer that the left front.

Now, moving on to the head - the lack of the eyebrow is a very daring feat, but you managed it perfectly! Well done! What I will suggest, is that a horses head is never exactly strait - maybe if you add a slightly dished effect - or maybe a roman nose - nothing drastic, but I always think it looks more realistic that way!

I love the way the background is so beautifully simplistic - it draws the viewer strait to the horse, and the beautiful details. Maybe a cloud or three would help to break up the blue though? Your call!

Now on to my absolute favourite bit - the hair! The combination of colour and shades is beautiful - it really looks realistic (well, as realistic as a green mane and tail can be! ) You even got the fine stray hairs right! The fact that there is no lineart is great!

Sorry this is long, but by no means is it bad! Infact, I love this peice to death!
