What is the best way to implement CQRS without ES?

Question

C++ / C#

I am developing an application using the CQRS approach.
I implemented this approach in the following way: GitHub link .
I would like to know the opinion of more experienced colleagues about my implementation of this approach. What would you fix? Perhaps I have implemented CQRS poorly at all and I should rethink and rewrite everything.
How would you organize work with models (see MyApp.Movies.Queries)? I decided to place the models next to the requests. But what worries me is that in some cases there may be code duplication. Is it worth moving read models to a separate project?
