Transition between the table/floor and your background is a little too abrupt (IMO). To make the transition line softer, move the subject further away from the background and shoot more wide open to decrease the DOF.
Very nicely exposed shot - nice trade-offs between the dark on teh bellows & ring around lens with the start white on the box. Your title works against you "new" and the condition of the box don't match. You'll probably get complaints about the "harsh shadows"...
Nice product presentation. I'm sure what you're selling. Lighting is good and B&W works really well. I'd use a different,less centered, comp to allow for text in the ad.
