I feel like the attention centers of your work (foreground) need more details in them- for clarity's sake. I would like to see more lines on her mane, for example. Your backgrounds, however, are amazing; the shaping of the whole composition is in good harmony with the colors. I still think you oughta put more defined details in the foreground, simply that there's more to look at. You're doing great with every edit I see with this piece.
