My first thought was that the 'sketch' was mostly 2D. Looking more, it seems that it might be real hands. If so, very nicely done! Conveys the sketch feel perfectly. I'll be curious to see the description...
Nice idea and execution. Nice duotone choice, can understand that the metallic feel/processing is intentional, but overall image feels too gray - please consider adjustment to brighter levels.
This is excellent! From the thumbnail, I thought you took a picture of a picture and was wondering was it wasn't DQ'd. Then I opened it and thought "WOW". I couldn't possibly tell you any way to improve it so I'll just tell you I gave you a 10!
good take on a very tough idea, but the post processing to mke it look more pencil sketch like doesn't work, I just mkes the work look like a poorly processd photograph, especially across the knuckles. E for effort.
