interesting idea, but unfortunately, it seems so set up that it takes away from the impression of actually 'stopping motion'. it also looks like the knife is going to wind up a bit off target ;-)
"Great Job" from the "Great Job Baggie"! I love shots that are humorous and light-hearted. This is VERY original. Did you draw blood at some point? LOL. The hand drawn circle is just brilliant. The imperfect drawing on the hand (unevenness of the circle, and crookedness of the lines in the circle) are very nice. The tonal quality of the background allows your subjects to stand out. Did you dodge and burn this one? If so, then maybe the one thing that I'm seeing in here, that I don't like, maybe a result of that. What that one thing is, is the lines on the hand and fingers seem to be a bit blackened. That could just be me, however, but I find it a TINY bit distracting. I'm upping your score from an 8 to a 9 after second look. Just because it's funny and original.
Talking from a person who is afraid yet drawn to knives, this image scares me a bit, its nicely done.
But the fact that the knive, seemingly, would not hitt bullseye bothers me a bit and also the shadow/dirt on the thumb.
You weren't a Boy Scout were you. ;^) Funny idea. Somehow the split fingers between the index and middle, adds to the image in a good way. Thumb is a bit tight to the right. The knive isn't quite as sharp (no pun intended) as the hand - it's a little blurry like aperture wasn't deep enough to get it all in focus.
I'd like to see different lighting used as it seems to washed out. Also maybe moving the knife in between the pointy finger and the thumb would be better. Right now the hand makes me think of monkey feet. :)
