First concerto Grosso (quartet harpishord reduction)

I need somebody to check somes counterpoint rules and to help me to work on the maybe strucure or harmony?

I think before anything else, you need to work on the ritornello theme a little - it is for the moment way too short. The descending fourth - ascending second harmonic sequence you have written so far however is fine.

Afterwards, think carefully about what you want to do for the stuff between the ritornello theme statements. There isn't really a particularly interesting melodic line at the moment.
