here is my attempt at an advertising product shot... constructive criticism is welcomed but keep in mind that I'm just starting out with studio photography, this is my second attempt at a product shot

You asked for it - so, here's my take . . .
1. why is the bottle still capped? And what is that 3 little beads at the very top?
2. The ice at the bottom of the bottle? What is that? I'm at a loss of how to describe the over-all effect. Put it on a bucket! If you have those ice all-around then shoot the product inside the cooler at least.
Here's what I would suggest:
Open the bottle, tilt it a bit like it's leaning on the glass, take a tight shoot of the upper 1/3 of the product.
Close down your aperture to get the bubbles and the neck-logo in focus.
Tone-down your lighting so it does not wash-out the logo.
Take a shot of the mouth of the glass and you'll have a winning presentation.
