With my photos from this photoshoot, since the theme around my board is memphis which has lots of geometrical shapes I was thinking of adding shapes into the background and around my images. Though I think I might retake these photos in front of just a blank wall or something that fits my color palette (pink, blue, yellow) more because it will be easier to work as the green background of the plants in the photos I have taken don't fit my color palette or theme at all.
As for applying gestalt into my posters, I want to play around with the similarity and common region aspects of gestalt. In some of my posters I have already made I've been playing around with similarity by repeating silhouettes of different instruments.
