What is the intent of this?
Are you building a portfolio and want to focus on product shots? Or is it just for experience?
Coincidentally, I'm doing a cologne shot myself right now.
But it will be a hybrid project where the product is totally synthetic (3D generated) and comp'd in to BG.
It's also a fictional product because I'm creating a portfolio to show off product photography in hopes of getting into advertising photography and conceptualization.
I did quite a bit of research on the subject.
What I found was that it's best to shoot against a standard background, not a outdoor or staged environment.
Just a monochrome backdrop with the bottle standing upright, showing the different sizes the cologne comes in. Possibly with some objects in frame that pertain to the theme of the product in some way.
Another option is to shoot it on what looks like a perfume department case with a high DOF so the product pops out.
In your image, the background is much too busy, the product is slanted, the label is obstructed and there's nothing else related to the subject in frame.
These are big 'no-no's' in advertisements.
If you don't want to do a standard shot with a simple background, try taking a shot of the cologne bottle, then some sort of photo that relates to it, then comp the cologne in to the side or bottom of the image.
For example, Nautica cologne always used some sort of scene with a guy, a girl, and in the BG is a sailboat or boat docks.
The bottle isn't actually in the scene, it's against a studio BG and comp'd in on the side of the photo as to not distract the viewer but to emphasize how the scene relates to the product.
I'm just using a monochrome gradient BG with no reflections or specular, a speckled floor with nice reflections, a unique appearance for the bottle glass material, a couple of BG objects to bring out the DOF and some exaggerated creative lighting to bring the viewers eye to the product.
I'm not saying you should do it like I do, just saying to keep it very simple, aesthetically pleasing, with focus on the product.
Since after all, were this for an actual ad, you're showcasing a product so it should be the center of attention.
