It may just be me, or my screen settings, but the lower knife seems to be rather blurred and too dark in the shadows. I'm not sure, but maybe if you enlarge the depth-of-field a little? An add a very subtle light at "bench"-level, somewhere near the bottom-right corner (shodows, off - just to give a hint of "presence" to the lower knife. Of course, I might be talking complete bllcks, but it might be worth a try:-)) Cheers, Diolma
