My Edits
In Photoshop, I drew around the outline of all items with the select tool in order to place them on one black background. I altered the size and rotation of items to give perspective. In the above image, I placed all items that consisted of plastic material.
To eliminate more black space, I took the items of one image and placed them over the other.
I also liked the look of some of the items when they were on their own as although they were minimalistic, they encouraged the viewer to imagine the stories behind these items.
