Maybe too shallow depth of field, it would have been better to have the whole part vertically in focus... Good colors and smart blending with background...
Needs a deeper DOF. Are you only trying to show us the first two drill bits? Do the others not matter? Are they just there to fill in the fluff, to meet the challenge requirements? If you had placed the others in better focus, the overall impact of the image would have been improved.
Nice idea, but the DOF in this case is a bit too much. You loose drill bit #7 into the blur. I'd also like to see a slight rotation of the leading bit so I can read a bit more of the text.
