I’ve heard a quote attributed to Robert Capa, “The main difference between an amateur and professional photographer is the professional has a larger garbage can.”
I main advantage of digital is the economy of shooting unlimited images. If you have a high GB card, or a place to offload images as you shoot, you can try a large number of settings to get the image you want.
If you go on a shoot with 10 rolls of 36 exposure chrome, then you have 360 exposures (maybe 370 if you are careful on loading). So every misstep or screwed up setting has a real cost in processing and lost shots.
The main advantage to experience is to cut down on the number of bonehead mistakes and increase the number of good images for you to choose from.
The only problem with making mistakes is not learning from them.
One plus with a 10-14 MP camera is it will allow you a little more cropping room. It is the same advantage that a 120 camera gives you over a 35.
The 10-14 MP cameras also tend to have the latest and greatest metering and other bells and whistles that help you make adjustment at the time you are shooting. With RAW option you can make those adjustment when you at the computer. When you are in a hurry or need a take a shot on the fly RAW can save your butt.
Photography is about more the resolution. A beautiful composition can be hurt by a lack of resolution, but the inverse it not true.
