Beautiful model - but gosh that pink neon hat is UGLY! But without it - I guess there is no neon - so it has to stay! Nice composition and exposure. Catchlight in the eyes adds more impact. Nicely done.
The model needs to be placed further from the background. When the model is shot so close to a background, the composition has a very claustrophobic, compressed feeling. It's a nice pose and the cropping is good but the lighting appears harsh and unflattering. I like her hat but it isn't a cowboy hat so the title is a bit confusing. Also, she is pulling at some pink lining (or something) from the inside of the hat and that is extremely distracting.
