One challenging aspect for me was to have the composition look right with vertical orientation. Being able to fit the story telling object in without including distraction elements.
I used f/2.8 to have background blur, but on some of the shots I wondered if the depth of field was to shallow. How much or little of the main subject (in this case the hands) should be in focus and the image still look sharp?
Also, to help with the lighting I used bounce flash.
