I think you are off to a great start. Really like the top one!
You've done a good job of paying attention to how the actor relates to the environment. As your daz-fu skills increase, you can try things that will allow the body to morph/interact with the environment (like how the calf in the bottom picture would flatten as it contacts the marble floor etc).
The real trick is to get the fabrics to lay naturally... I struggle with it myself.
If these are dForce clothes, you can try and simulate them to get them to fall in a natural way.
Otherwise, really nice!
