You were able to capture a nice reflection. I would try this again from another point of view. One that captures all of the products (none of the product cut out from the picture) as well as the reflection.
I would suggest more of a straight on shot. As much as you can while still capturing the reflection.
I would also suggest putting it all on a dark b/g, maybe some fabric.
I hope this helps....feel free to pm me if you need clarification on any of this.
