I like the tilt and the way you displayed the product. Comp could be a little more "rule of thirds" to give room for text without ruining the balance. Also a fill flash (or a light tent) might get rid of the distracting shadows.
Though positioned at an interesting angle the lighting is very harsh.
Using a diffuser would have helped greatly with this. Use of a shallower DOF and positioning the phone further away from the background would help to soften the transition lines in the backdrop.
