This image has all the necessary features as a realistic render. You chose great morphs, textures, etc. that hair is great and I wish I knew it. What makes it a very good image is what you've added of your own: a carefully crafted pose, beautiful cloth posing, and great lighting.
Your post work choice of the framing crop and keeping the hyper realistic clarity of the textures works very well.
There is a wonderful symmetry between her eyes peeking out and her genitals doing the same. Always hard to know how much to show without having the art simply fade into cheesecake. By keeping her top on, you have chosen our focus well. You have done this just right in my opinion.
Very nice picture, i love the balance of the colours, the somewhat bland white lingerie really brings out the red in her hair. I also like the tease of her lower her bottom, sexy and smart.
This is simply an amazing picture, posed professionally, it looks incredibly life like. Your image is also finely cut down to size so to speak, you have left just enough room that it gives you some idea about the background, but just enough that it really focuses your attention on the model.
Very fine job Sapphire, you ought to be proud with this stunning picture
