What is crucial in 35mm work flow to get great result IMHO is that you need to be careful on very step: from choosing good lens, nice film, careful developing, checking temperature during developing, printing on great enlarger with great enlarging lens, perfect align enlarger and so on. Watching on every little step and perfecting your work will give excellent result on the end. Medium format is more forgiving (my experience from time when I was using 35mm and 6x6).
