so I teach LSAT classes, which is obviously extremely different from photography, but I think one principle (at least one) applies very clearly here.
Practice in and of itself does very little. You have to be practicing something. You have to take some technique that you're trying to learn and practice that. I can't tell that you're doing that. From your posts, it just looks like you are kind of taking a lot of pictures and calling it practice. Now, don't feel bad, a lot of people do that, with everything in life. But before you practice, you need to have a very clear view of what you want to do. Without a clear vision of what you want to do, all you are doing is practicing bad habits.
Every time you are practicing, remember, you should be practicing some specific technique. You should have something specific in mind that you're after. You should spend at least as much time personally reviewing your results, trying to figure out what you liked and disliked about each of them as you do taking shots and then posting here, and then listening to the cacophony of varying responses. You need to first review all of your images and try to figure out, as best you can, yourself what was good and bad about them. Sure, outside eyes can help you find things you missed. But C&C should be secondary to your own personal reflections on what you got right and wrong.
When you are practicing you should review every image, reflect on what your intent was, reflect on how well you pulled off that intent, what you could have done better to pull off that intent, see what you can do to fix it and try again. Here it looks like you just shot lots of images, posted them here, and awaited comments.
While photography is about capturing very small moments, it's really, from a photographer's perspective about thousands more moments leading up, the building of the image, be it instantaneous and candid or in a studio. The building of the image. Even if you're just shooting your kids, if you want photographs instead of snapshots, you need to think about them a lot more in advance. Especially at first. As you gain experience, then you will be able to grab your camera and take a well considered photograph quickly, because you will have built all the things you practiced into habits. But right now you'll need to spend a fair amount of time thinking through the steps. I know that sounds like a lot of time to just shoot some shots of your adorable little kids, but that's why it's photography and not just snapshooting.
So, I guess my main point here, is your biggest issue is that your photographs need to be much more considered. You need to think more closely about what you want out of that photograph, and then what technical demands are required to get it.
Im by no means a great photographer, but before I take a shot, my thought process is something like this:
1) What am I shooting, where do I want to frame it? Where should I move to in order to get to the best point of view for this shot? When will the moment I want to happen actually happen?
2) Would it be practical to shoot this with a tripod? Monopod? Gripster? Beanbag?
3) What is the lighting situation? What ISO should I be at? Do I need flash?
4) What kind of depth of field do I want? What f/stop should my camera be at?
5) With those two settings, is my shutter speed fast enough given my focal length and handheld/tripod?
6) Take the shot
7) Reevaluate steps 1-5 very closely try to figure out what would make it better
8) Take it again
And that's kind of the bare minimum of what you think about for every shot. A lot of times even more goes into it. And yes, it's very hard, and very slow at this point. I get a lot of it wrong. But the key is when you're considering those things and more, very closely, for every shot, you're actually practicing, instead of just taking random shots. Taking random shots isn't practicing, it's just putting shutter actuations on your camera.
