This is really good. Beautiful model, relaxed but appealing pose, the colours are nicely melded together, you have interesting shadows and make a good use of space. The thing is, though, that I find my eye drawn away from the model. The space on the right is distracting. There's a lot more going on there than with the model in a way. The shadows kind of lead you in that direction with their curved path and then apart from the regular doors you also have the reflection of what I imagine are the roof tiles on the glass. It's just busy. Plus, in that same section of the background you have yellow on the ground which also happens to be the only colour that the model is wearing that helps her stand out. Also the way the shadows fall over her do help connect her with the rest of the scene but in a scene where she needs to stand out that might be a hindrance. Adding a more vibrant colour to the model may not work in this context so I would have suggested maybe a shot with her standing- maybe a more commanding pose that cuts across the background- not quite in the center but close to it. Something to make your eyes go "bam! there may be other things in this picture but look at this model!" Lastly, though I like the way you pulled things together through colour maybe it would have been best to not use so much filter. The terminal is basically all grey. You would have had that one unifying color and then her standing out because of her skin tone and bright clothes... In theory at least- i'd have to have seen it before to be sure. Other than that, your focus and composition are very good.
