IMO, & after viewing your work you have on flickr. I don't think you need to worry so much about gear rather than finding your vision & style. Gear will take you so far, but working on your creativity will do you more wonders than any MF system will ever do for you. instead of just lighting the scene, you need to do more than just light for the sake of light. Struggle with what you have now till you've find your niche. It the only way I believe you will become a better photographer.
