The second one is cool. I like the effect but I can't look at the background too long, it makes my eyes water. I find I do have to concentrate on the person to make sure he is sharp.
#1 has a really nice eeerie feel about it.
Both are excellent. The IR does the first image well.
The second is also great. The blurred background make me feel like I am falling.
Both are well done.
spooky stuff, great IR shots. Background on the 2nd one is a little bit too much, but does make the subject more surreal (if that's what you were going for).
