Secondary Research - Photography Idea

I have gathered some photos from the internet of the ideas I have relating to the photography idea.

These two images are simple head shots. My original idea was to do something like this, with lighting that relates to the emotion I am trying to showcase. However after looking on the internet I'm think of doing different styles if I choose to go with this idea. 

These images all capture an emotion. There are various camera angles. The last image shows stress or worry. The camera angle captures the emotion perfectly. The camera angle can add a different element to the picture. There are also different types of shot; close-ups, wide shots etc.

There are many possibilities that I didn't consider when I first thought of this idea. Whether to add a prop to add an extra dimension to the image. Or maybe another person to add extra emotion. Or whether to have the images serious or funny, like this last image. Looking at it I can't take it seriously because even though the expressions show emotion, it is done in a humorous way.  

I would like to see if can recreate some of these images and try some of my own. Hopefully in the coming week I will be able to.
