That red pencil nude is gorgeous!
You've chosen great colours for this latest one and done a really sweet job, but I have a couple of little things that should be noted when drawing lingerie...
The first is that her panties would normally be under the garter belt and the second thing I would consider is that because she's using a belt with straps & clips, wouldn't reeeeally have a need for the thigh piece (unless of course, she needs a place to hold her money clip or perhaps a discreet weapon
Other than those very tiny issues, I think you do some stunning nudes. As I mentioned, I love the red pencil one, but the laughing nude with towel is so sweet and probably my favourite!
