I think the questions you ask in order to start an open task are sometimes not very clear. So giving an answer that makes sense to the question can be tricky sometimes. For the rest I think its good, although I think it could use more images/ video etc. I really enjoy the choice exercises, it really puts you in a situation.
I think the methods and approaches presented here are really useful. In terms of application and practice a lonely online course is difficult for assimilation. Some exercise in group would be a really good complement and increase motivation
