I like this two photos by my group work,because the white happy mood photo with the skull hands up is totally opposite to the photo on the right which the dark death mood of a skull head hangs up on the pumkin,one is very foolish and bright,other is dark and creepy。the composition of the first one is on the center and brightlight,the second one is rule of third and sidelight 。
This is a really good example of taking the same object and transforming it with composition and lighting.
