Admin Panel - UI/UX Process

I'm working on designs for a new admin section within a product I'm designing. I wanted to show some of the process I have taken before I began the high-fidelity mockups. I started with some sketches of how the main screen of the admin panel would be laid out and organized. I also worked on some user flows to plan out the designs for the required functionalities. The last image shows what I have so far for the high-fidelity mockup of the main screen. Next steps are to sketch out the screens for the additional flows. [Click on images to view full screen]
