For my vector portrait I chose to use a photo from my elementary school days. I was far easier to look at back then. I started the process in Photoshop by adjusting the levels so that there was a bit more contrast and then posterizing the image to create more defined shapes and colours.
Once this was done, I brought the image into illustrator and traced out the different elements of the portrait such as skin, hair, eyes, mouth and shirt. I used the original photo to help sample the colours to get the right tones.
To help define the face a bit more, I added some shadows and highlights using the pen tool to define the area and the blend modes to darken and lighten the areas as required.
Additionally, using a custom-made brush I added some individual darker and lighter hairs to add some texture and eyelashes.
Finally, I added some details like buttons on the shirt, highlights in the eyes and texture on the lips to add realism to the portrait.
For the alternate, I went with the blue monochrome look to add a calm feeling I seem to have in the photo.
