This example of photomontage works well because it is visually interesting and has a lot of contrast. The photo of the woman is in black and white while the photo of the plant is shown in color this contrast makes the image stand out more.
The collage creates an interesting dynamic form. Overall, it comes off as a statue because of the solid shapes, and it's well grounded. It has an uplifting motion because everything is point upwards, and has a stacking movement.
