This is fantastic portrait! I love the way the depth of field is used to bring in a lot of color but not be distracting from the clear shot of the face, also a great profile. The background seems almost an abstract wash of color. I get a very aspirational vibe from the mood set by everything here.
Also a great use of the square framing, I don't feel like I am missing anything like I sometimes do from a square portrait. I might like it if the image was pulled further back and paned left a bit but I can't say for sure.
