Welcome to the final circus all the choices are great but remember simplicity and ease of use. Let's go with art design - get a feel to it. A texture. Log in and log out - to do your thing. Get it done and get out. Leave no messy trail , leave no 10 step process for a text line. You will understand you will make it usable , they will believe they will see. It is all - right there - already - do what you know - it already works - no need to mess up something that works. You might not understand at the moment but it is real. Stay tuned.
