Instead of just pointing right at the bottle, he got down on the same level of it and put it off into the left third of the frame while still making sure the rest of the frame was filled with other things.

Here's one that I took recently. There were a bunch of these valves with pressure gauges on them that seemed cool enough to deserve their own picture but I couldn't find a way to get them in a way that I liked. I started trying to get more creative with angles and squat down in front of one when I saw this. I put the gauge in the right third of the frame and let a big panel fill the background. The blur on the panel and it being darker helps separate it from the foreground.

Here's another I got of some cars in the woods. In this case my subject is in the midground. I put the car on the left side of the frame and got in a position where some other stuff would be blurred out in the foreground filling the bottom right of the screen. I also got right down on the ground so the leaves would add more of a sense of depth. Being zoomed in and going further away will help with this.

To sum things up, don't be afraid to get right down on the ground or in weird positions. Look for other things that you can use to frame your subject. While it's often easiest to just use the widest angle you can, try zooming in and trying to add more depth to your shots. If you have any other questions feel free to message me.
Hope this helps
