I really like this piece, the way you used different textures to heighten the sense of depth. Cloud-Chase could look a bit wetter, maybe more work, hightlights and such (I'm not a professional, lol) on her wet mane and tail, but I do like how you did rain bouncing off of her and the rocks, making it look more realistic. The darker purple, green, and blue tones make this piece stand out, and the grayscale Cloudsdale in the background. I especially like he tall mountain Cloud-Chaser is standing on, though I wondered for a moment where in Equestria you would find a mountain that tall. Then again it IS a land of magic and ponies, so I dont have much to say. As for the lighting, I think you did a great job, though it could be the tiniest bit darker in the bottom of the image, putting more emphasis on Cloud-chaser.You copied the MLP style flawlessy, and you were still able to add your own unique touch. Keep up the great work!
