I drew the picture and made several copies of the picture, slightly changing the different moving parts each time. I put all the photos in the same picture, made them into an animation, and saved it as a .gif.
I took a whole bunch of photos while moving the camera around, and put them all in the same photo, moving them into the correct order and lining up different landmarks.
I took a picture of myself with the same facial expression as Valkyrie. I replaced her face with mine, lowered the opacity of my face, and changed my skin tone. I blended my face in so it looked normal.
I took a picture of myself with the same facial expression as Black Widow and placed my face on top of hers, changing my skin color, adjusting the lighting, and blending it so that my face doesn't look out of place.
I took various pictures of myself and things that I enjoy and placed them in a montage. I placed text boxes on each picture with a text that describes me.
