Amazing, especially the first one. Lighting can play such a huge part in photography, it can make or break a shot, and I think in all of these shots they're done soo well. I might have to borrow my girlfriend's Nikon d40 and take some interesting shots, see what I can manage. I think everyone should do the same! I know soo many people have decent cameras that can take decent stills, but a lot of people seem to think its all about video footage + getting subscribers on youtube. Photos are much more amazing, if done right, in my opinion, and I'd love to see more from people!
