Does this itinerary make sense?

I posted some itineraries earlier but I realized they were a big mess. We tried to cover too many regions. So I condensed somethings. How does it look now? I have two versions. They are basically the same route but in opposite directions. I'm going with friends. We are trying to avoid tourist spots, get some good food and also see a bit of nature. We are trying to avoid driving if possible, but I know that might be difficult in some places, I'm assume?

I am wondering if we are overdoing it. Should I reduce it further? Is there something I did not consider? Should I be spending less time in some vs others?
