Your depiction of the landscape and the nature in this world is beautiful and quite detailed. I love the waves crashing against the tall cliffs, with the forest perched precariously on top. The mountains in the background are equally amazing, brightening in response to the sunrise.
The lighting is also very well done - the way the light illuminates the sides of the rock and the zebra are amazing, and help separate the focus of the piece from the background. The lighting provides a believable 3D feel to the zebra, who looks like she is completely in tune with the surroundings.
Glorious lighting work, both on the landscape and on the foreground rock and the zebra. Lovely hair texture and detail, too. The shading on the body gives it a proper and good-looking shape, and the tones of the rock are perhaps no less interesting to observe, as they're quite complex, in a good way. Great job once again.
