I took a picture of myself in photo booth and transferring it to photoshop.
I cut my body outline and layered via copy.
I then cut out my hair and layered it via copy and filled it with a base colour.
I continued doing this for the other parts such eyes nose and mouth.
For my jacket and shirt I coloured in the clothing creases and outlined the entire body and the jacket and shirt I finally filled in the colours of my jacket and shirt
