My plan for early september. Any advice for the way back?

The waypoints are camping spots i will spend 1 or 2 nights. I am not focused on visiting big cities, bit rather nature and sights. Of course i will still dip my feet into Venice and Florence, because they kinda close to the route.
Should i got through Lake Garda and Austria on the way back, any other tips?
