Hey thats a good start!
The first thing that throws me out is the blurred background seem to be at a differnt angle to the table top? Then the blue table definitely doesnt work.
If you want to have the JD bottle as the main focus, then thats what should hit your eye first...
Also, the shot glass could do with some more detail, liquid or whatever but maybe a label on that would help? If you straighten up the camera and put the glass closer but switch on DOF and focus to the bottle that would be nicer... Check these ref pics out, notice the detail on the neck of the bottle.
Godd start! Keep with it, dont get bored
