Feedback of a CEA?

Hi! I’m making a Cost-Effectiveness Assessment (CEA) for a Finnish charity that has a development project in Nepal, in coordination with a local charity. This is the first time I’m making a CEA. Would someone like to give me feedback on my work? Here is the current version: https://​​docs.google.com/​​spreadsheets/​​d/​​1TEIID00c-5Wgt93h9MdAWykiG8tX7KtrflQs1g-vsTU/​​edit?usp=sharing

Thanks!
