These photos are really amazing! Bravo.
But don't be confused as these are simply the results that film can do and they would be the same or even better if you were using a Hasselblad, a Pentax 67, a Mamiya 7, a Bronica. The easiness of use is a great advantage of a camera as it helps you to take more photos and in a more pleasant way.
All that I want to say is that first you have to try to become more familiar with your camera and if this is impossible to you then I am sure that many other cameras can replace this one...
I have most of the previous cameras but finally I am using my Mamiya 6 almost all of the time just because it's a pleasure to work with.
