Deep solid blacks with pure whites and a surprising spread on the tonal range considering almost everything is black. I find the splodge of light in the top right a little distracting and it competes with the aperture marking highlight behind the focus ring. This would make a good product shot with composition as it is but with dark deadspace at the top of the picture - but for this challenge the composition is spot on
The detail in the focal area is good, but the handle/tab in the upper center has an odd look to it. Maybe the sharpening didn't take so well in the "bokeh"?
