He has a great smile! I wish you showed us more of his winning smile by zooming/cropping closer to his face. There is just a little too much background that dominates the scene. A square crop that would end just bellow the shoulders and just above the head would truly allow that cheek to cheek smile to shine. B&W would also help this portrait shine even more because the color clash of the muted orange of the shirt against the forest greens of the backdrop draw attention away from your main focus.
