2.5 month itinerary & budget

Hi! I am finalizing my itinerary for my upcoming trip from March 6-May 16, and im looking for feedback on my plan. It would be 71 days, and I have 5000 USD saved. I will be budget traveling by staying in hostels and cooking a lot of my own food, as well as staying in less expensive areas, besides Amsterdam (but the flight there was cheap). Anywhere you would cut/add/avoid? Or just general advice as this is my first solo trip! Thank you :)
