I like this one best so far because...well...it just looks so damn real! When I first saw it I thought you were the next Dale Chihuly or something and this was just a photo. The organic shapes and the swirls are ridiculously eye catching. The only thin i want to whine about is that you rarely use blue. Can I request more blue? Ha ha. Sorry.
Really nice render. Is there some kind of self ilumination on the redish material it seems to glow, just stunning. I really like this, I think the only thing I could possibly suggest is maybe having a continous soft "pillow" for the model to rest on instead of a boxy hard edged room. But the room looks perfectly nice so thats mostly just a matter of preferance. Great work.
