Being a pro has almost nothing to do with your photography. It's about running a business.
I think your photographs both have potential. The first one was a contrasty hot mess, but what the hell, it has a lot going for it too. It's graphically very strong because of the big white and black masses in it. The kid's cute as hell, and by blowing out the skin you made it look smooth and wonderful. The eyes came out a little weird, for some reason. The second is great, except for the skin tones which someone else pointed out look pretty weird and unpleasant. It's a much more strictly correct composition, and I found it less ultimately interesting than the first one.
You're shooting entirely by instinct now, I suspect, rather than with very much formalism. Be ruthless in your editing, throw out pictures you don't like and try to figure out why you like the ones you do like. Make prints, and stick them where you can see them.
If you want to be professional, you don't need much in the way of photographic skills, but you *do* need a signature look, so figure out what you like, what you can reliably do, and try to turn that into something that people "out there" like and try to find a market for it. Also, you probably need some more gear, people love a photographer with a bunch of expensive crap (I am serious, here, even though I sound sarcastic -- either have a bunch of gear, or figure out how to run your business in such a way as people don't see your gear).
