I think that picture looks just fine.
But you should keep in mind that the color background you use can make the color of your product look a little off. If you really want a white background, try taking pictures outside or by a window with natural light. You should also be able to adjust the white balance on an editing program or through your camera settings to help get the real color out of your product.
I take a lot of pictures on a white poster board or a blank sheet of paper by the window & you'd be so surprised how nice your photos can turn out with a little natural light!
HTH & keep up the good work.
