Welcome back Roman89, and thanks for the new renders in stockings, yummy!! Not too sure with the first one for Martin, he looks very awkward and crunched up, but maybe that was your intention. D looks stunning in these renders, but as an unashamed fan she would look good in a plastic bin liner!
Not knowing the renders you mention, but i think you might be too critical of your own work, but then most good Artists do that anyway. Why not post them and see what others think, then you will have an informed decision. That´s if you still have them??
As always my friend, keep doing what you do, and maybe sometime you could join others to make your own VN?
