Realistic South America dream trip; itinerary, tips

Hello,

I'm planning a 6-7 week trip through South America in around 20 june - 3 august. Im going alone, its been a while since i traveled alone, and I never went to LATAM.

I would like to start in peru, spend most time in bolivia, and then visit chile before being in Buenos aires for a while. I thought it would be simplest to start from above(hoping Cusco has a big airport) and taking buses or trains around (to save money and to also see environment) making my way through bolivia, chile and to Argentina.

My preliminary plan is about

• 1 week in Peru (Cusco, sacsayhuaman, macchu picchu)
• 1 week in Bolivia, La paz
• 1 week going to Bolivia, cochabamba, villa tunari
• 10 days in Bolivia, sucre, samaipata, potosi
• 5 days in Bolivia(uyuni) and Chile, San pedro de Atacama.
• 10 days, flying to Buenos aires.

I made a map of what im intersted in seeing (https://www.mapcustomizer.com/map/wowprimita), but I am interested in also just relaxing and "breathing the air".

I want to see a lot of stuff and therefore I made the map with some "sightseeing"plans, but I also want to see the wild/jungle.

I am open for suggestions.

Im wondering if this is realistic, timewise, economically, and energywise, since i dont have experience of this. Do i have too much planned? Flight/trip planning recomendations is appreciated.

Any tips or recommendations on is appreciated, gracias.
