Acne Self-Assessment App UI Concept

Presenting my Acne self-assessment App UI concept. Please share your thoughts / feedback.
App enables the user to perform self-assessment of acne. I aimed to present data in a coherent and clean way using visuals. Graph 1 represents the mapping of facial acne regions. Graph 2 represents analysed data.
The user can apply historic reports on the same graph to view more comprehensive analysis.
