There's so many impressive parts to this. The big ones for me were the silky effects on their lingerie (always had a soft spot for that glossy look and I love how you've painted it; also love how you've used it to make that marble look top left) and how you've used texture on some of the surfaces (particularly like the sparkly look on April's panties, bra and tops of her stockings, and think the leather sofa is just perfect!). Felt the lighting from the fireplace in the background is a lovely touch too that really adds to the dark colours and shading.
Nice job I gotta say; you've got a great eye for lights and darks and I love you you approach shading. (I'm just really sorry it's taken me so long to actually get around to commenting; faved this ages ago and always meant to XD).
