great, but it feels a little disjointed, for instance the boots have a lot more contrast than the uniform and face. The perspective in the background boxes could match the figure better. The crossing lines of boxes are distracting from the simplicity and elegance of the figure. Its a little hard to see the figure against the green background, maybe shift the background a little bluer so the figure pops.
the rest of your work is so good, this feels a little weak in comparison, some of it comes from the drawing.
