The emotion I expressed in my portrait is happiness.
To create this portrait I photographed my little brother on a swing set. 
I posed them to have the sun behind them.
I used rim lighting to.
I edited the image by making my model more sharper, I made the background more lighter, and lastly I make the shadows standout more. 
Overall I think my portrait was a success because I captured the right emotion I was looking for in my model.
