I created the background music using Garage Band looping tracks. To balance the overall sound volume, I had to reduce the levels at different points at time, such that when the talking head is speaking, the music would not cover his voice. I also adjusted the master volume with a hard limited, then used a loudness radar to target the loudness at -15.0 LKFS.
In terms of the visual part, I converted some clips in Premiere Pro into After Effects composition to add motion graphics. For the parts where the text overlays across scenes I create new compositions and adjusted the layer size on Premiere Pro. Another challenge was correcting the color. Since shots are taken at different time, and the indoor scenes were rather dark, the tone of talking head was too red, causing inconsistency in the overall mood. Again, using the color correction panel I balanced the RGB values similar to color correction in Photoshop.
