Premise: Further Visual Development

I want to use brighter colours to make everything seem busier, but I don't want to make it unreadable. I might take something like second image below, where only parts of the background are shown, to keep each shot more simple. I like the simplicity and contrast in the first image and I do want to keep the red I have been using.

I want to give my character a face to show myself emotional reaction to the physical sensations I experience. I want to keep this simple, but expressive.
