Raffay - This looks like a well-exposed negative to me. You've got good detail in the shadows and no overblown highlights in the sunlight background. If this is is a straight scan of the negative, there's no reason you can't get deeper blacks and more "punch" in the image when you print in the darkroom or post-process. If you had underexposed/overdeveloped the film, you would see more contrast, but at the expense of highlight and shadow detail.
Can't answer to your problems with sharpness except you will want to use smaller apertures to obtain enough depth-of-field throughout the scene, especially with landscape and scenery shots. If this is 35mm shot, I would shoot at no larger than say f11, which (on a 35mm lens) will means everything from 2 meters to infinity will be in focus. If you took this at 2.8 or 5.6, some areas will be unsharp, depending on where you focus. If you're using autofocus (and it's malfunctioning) I would switch to manual focus.
