This sounds like a possibly interesting project, BUT...

I've been reading the claims that PRiVCY would be an improvement of DeepOnion, from which the code and distribution method it is copied from, but I have failed to find and explanation of WHAT would actually be the improvement. Could someone please tell me?

The roadmap on the OP is generically speaking of "improving privacy features", without any details, which in fact means nothing. Which are the improvement that you plan to impement? If you don't tell us that we'll have to conclude that you yourself don't have any idea of which these improvements could be.
