This series has proved to be very interesting indeed. You have composed very well. The images are well thought out, they are sharp, and have great tonality.
In this particular shot I would consider a bit of tomato sauce or red die next to the person's head... That of course would make the image a little "too" graphic, and might turn a few people off. It would also loose it's subtlety, so it's a personal choice thingie...
IMHO, you should take these to the next level, by making them as clinical as possible...
I feel that you're definately on the right track Terrence, and I look forward in seeing a hell of a lot more great stuff like this from you in the future...
I think this is a bit beyond alone... :-) 30 seconds looks good. And remember, 3 is the magic number! The odd angles you have been using on this series are great!
