How can i make this Better

use longer focal length to reduce nose.

1. Pose looks like she is talking on a hidden cell phone.
2. wide angle lens makes her legs look too thin (perspective)
3. crop at her left knee bothers me, maybe crop up her thigh a little.

Beautiful model, nice skin tone.

i'd do a 10X8 crop cropping out the bottom and then clone out some of the highlight on her back and behind her head then us USM 150 0.3 0 then print.

For me (and I am no pro) I would sharpen the eyes a little to make them pop more, and then fix the highlights in the back ground since they are drawing my attention (biggest item to left of the pic, behind her head).

For a pose, I would have prefered the hand on the head to be down with ther other hand - just my taste as I say.

I do like the image overall though, like the tone/colours - looks very natural to me.

Focus appears to be on the right shoulder, not the face.

Crop tightly on her face with some space camera right. This will eliminate the w/a problem and decenter the sublect. Sharpen her eyes.
