I would as far to say that this is my favourite thing that you've ever done. I love the hooves and wings!
If I could find one fault it would be that the tail is a little too big in proportion to the rest of the body, but that's really nit-picking. Hope you don't mind me saying, because I really do love the drawing!
This is good I really like it! And its huge too D: I think the only thing that could have been improved was the seperation between the colours of her mane and tail, maybe a hard line or something? Idk maybe I'm wrong lol. But overall well done
I was thinking about that. But then I thought that clear cut outlines would make the picture look hard, cold, and calculated; you don't want that if your drawing a sleeping pony The mane and tail were done with pencils ranging from B - 3B, I thought that was enough variation.
Still that's just my opinion. That said, I am very much pleased that you like it
