Hello anthroaf!
I think you definitely have a very strong application! But I think others will agree with me that sometimes we just don't know what each university is looking for. First, each university is different, every professor is different, so it's hard to know what they want that specific application year. We also don't know what each university values more, or if they value everything the same, etc... Sometimes people have really great qualifications and they don't get accepted because their POI wasn't taking students, or because there was no funding, or you know, many other random reasons. It's just such a complicated process!
Anyway, I think that with your qualifications and a good SOP and a strong proposed project then you really have a great chance of getting in! Good luck and don't get discouraged.
