Yeah, only some depth. It’s easier for me to explain writing things because I can just type up a new sentence to show what I mean. Art? Well, I’d need to redraw (part of) the thing myself and find somewhere to upload it temporarily. So I can only explain with words, and I’m not really good at explaining myself… or at least at making it short and to the point.
So, about the shoulder.
I can only eyeball it since there’s the wing in the way, but I’m picturing the curve of her body underneath and I feel the shoulder joint should be closer to the wing’s. Both a little more to the right and a little higher.
The big problem I see with the shoulder though, is that your mare is all curves… and I really mean all curves, even the tail bow’s corners are a little smoothed over. But then there’s this sharp, hard angle that looks like it’s been done with a set square sticking out of her chest. It’s basically two straight lines meeting together.
Only thing left I can think about is her ponytail. Is it supposed to be on the left side of the back of her head, like a singular pigtail? Because if it’s supposed to be in the middle, I feel it doesn’t look that way. Of course, I may be wrong, and maybe you don’t want even more work on this.
Though looking at it, I think it’d be a ‘simple’ matter of putting the (top of the) ponytail behind the rest of the hair. Don’t know if you used layers on this though.
As far as highlights go… I suck at light and shadow, so I can only eyeball it at ‘everything save the wings (as mentioned earlier) looks good to me.’
And obviously, all of this is my subjective, not-really-educated-in-arts opinion. Hence all the “I feel” and all. I may be wrong.
Finally, save for those little bits, the picture looks great.
(Removed the part where I’m pretty sure I mixed you up with someone else in this thread.)
