You did an incredible job on this, the shading looks very natural and the lighting is just right. The mixture of the warm and cool colours really give a charming and desirable affect. Scootaloo's eyes are incredible as well, they have a lot of depth to them and the tufts of fur that stick out from her chest give her a very soft and cuddly look. Overall this is a very amazing piece, keep up the awesome work!!
She's so adorable! You did a fantastic job creating volume with values, and the texture on her mane and tail looks amazing! I also love the lighting effects that emphasize depth in her beautiful eyes. Fantastic work!
