This picture seems a little dim. I do like the markings on the nails and somewhat the haphazard arrangement, especially as one point stands out backed by three very visible heads and a couple less visible. I find it a more powerful and compelling picture though when I crop it on both right and left.

You could've used less compression to improve image quality (your image size is less than 50K, limit is 150K). From this point of view, the nails don't look sharp at all, so it's not clear what you meant by the title. Otherwise it is pretty well done
