Not sure what you are attempting here. But it does nothing for me. I think if you want to make a portrait and include some long exposure time, maybe seeing the model's face in the blur would help.
Hmmm... I don't really care for this. The color is quite harsh, the amount of "movement" in the photo is quite distracting, and I'm really not sure what the concept is. I suppose in the strictest sense of "portrait", this is one, but I prefer to see something of a person's face in a portrait.
As a portrait shot, this doesn't work for me. I know you took a risk and bravo fo that. The photo is very interesting to look at and I have returned a few times to look at it.
Interesting effect. Not sure I like the yellow too much, but I think that's just a personal thing. What might help the composition here would either be to have the subject exactly center or off to one side or the other. As it is, it's not quite either. Interesting idea for a portrait.
