the first one is brilliant! smart way to setup the shot, nicely composed and all. i bet without a digital camera it'd be much harder if not for instant reviewing of the image!
personally i think it's not extremely difficult to get this shot because there is ample light at the end of the tunnel and it can be pre-composed. the most difficult part is the stunts itself, but i think you guys are really good at doing the stunts, being able to jump so high and all (i dun really noe the standards though), so that's not really an issue.
:thumbsup: saying "good job" is erm an understatement...
