I really want to like this. On first glance, it's very sweet and sexy.
I love the delicacy of her eyelashes, eyebrows, and mouth. She's a bit of a tomboy, but she's still female. The little details in the jacket and the individual feathers are also very nice. I love that hint of a belly, and the little touches of hair sticking out on her body, to indicate that she has fur. I love the way you did her mane, even though it defies gravity a little bit, and I also really like the shape of her face. It's perhaps a little too humanoid, but I think it works, and it's more interesting than the standard circle they have in the show.
But looking closer, there are too many other things that bother me.
Her wings have no truly defined shape to them. They're just a mass of feathers, and they look fake. I also can't tell where she is, because everything is white. I'm assuming she's on a bed, near a window, but I can't be certain. I also don't understand the significance of the papers, other than to liven up the background.
The arm that is lying on the mattress is confusing. I realize her hoof is tilted up to face us, but it looks like her arm is uncomfortably twisted. Even with my own arm in the same position, I don't think she would be relaxed for very long. I think it might have been better to have her hoof touching downward, instead of turned upward, or to have her arm bent so that her hoof is closer to her face. Or to have her arm tucked very closely to the side of her body. I feel this falls somewhere in-between what would be a natural position, at least for any length of time. As it stands, I can only think of her shifting out of it within a few minutes.
Also, the shading on the inside of the hoof is weird. If it is appropriately hollow, then the part that is currently shaded should be bright, and the other part should be darker. The outer exterior of the hoof forms a slender crescent shape, and the inside, where the sole is, would be curved inward a bit, allowing shadows to collect in it. Even when attempting simplicity, this holds true. If this hoof is supposed to be flat on the bottom, the shading still seems incorrect to me.
Looking at her overall pose, it also seems as if her torso is lying at an angle from her hips, and yet she looks as if it is being supported by an invisible pillow. Her back is arched more than it should be, if she's lying flat against the surface beneath her. Perspective doesn't account for this, unless her spine is curving towards the wall. It makes her otherwise perfectly acceptable hips seem disconnected from her upper body. I feel as if the line of action was altered at some point, and the overall piece wasn't corrected along with it.
And last, but not least, I think her eyes are downright creepy. They look vacant the longer I stare at them. She isn't focusing on the viewer; she's staring off into space, or else she is slightly wall-eyed. I can't help thinking that she might be dead, especially when combined with the awkward position of her arm, and that's what makes it creepy to me. ^_^;
I realize this is an already finished piece, and it was also a commission, so there's no reason to go back and change anything. But I felt like pointing out what I thought was wrong with it, to help out with future compositions. Please don't be offended.
