This picture is nice and colourful, while also very detailed. I can barely spot any problems with the picture, but the first one that I have to point out would be the missing footprints. Did it fly or were those just forgotten? Back to the subject, the colour and detail couldn't be improved but perhaps just the way the mane stays still as the horse moves around... Well, that's all I could find wrong with this picture. Very well done and if I do say so myself, I would rate this a 10/10 if the the mistakes had been fixed.
