The lighting, color and focus on the model are all very well done. I do think that I am not loving the fact that she sits dead center of the frame, with much of the white wall taking up space. I agree on the distracting background, and suggest maybe getting farther away with a wide open telephoto to get more background blur and a tighter crop on the model. If this takes away the feel of the base a bit too much, perhaps just moving around until her background seemed less cluttered. I will say a lack of real direction on this being about the model, or the base, and seeing so much clutter are making it difficult for me to feel some sort of emotion from looking at your photograph like one would hope for a portrait, its just hard to tell what you want this photo to be and what you want it to mean when I as the viewer see it, if that makes sense.
All in all a critique is meant to be a way to learn off of objective opinions so to recap mine:
-technical aspects of exposing model are good, you seem to be decent with the technical settings of the camera and such
-composition and framing might need a bit more thought, the creativity is not up to par with technical skill
I also see this was your first post, so welcome to The Photo Forum!
