After looking at your profile and posts you obviously have an artistic background and ability, sounds like you're working on refreshing or furthering skills with a camera. You can have great ideas but I think it's also necessary to have the technical expertise for those ideas to come thru in photos.
Like the girl in the red candy cane shirt, she's cute as can be and the photo is fun and the quality looks good of her, but the other girl isn't even in focus. It looks like there wasn't enough depth of field for both to be in focus. It might be worth getting out with just your camera and take pictures using various aperture settings etc.
It takes a lot of practice so you get to the point that you know what to do and don't have to think about it too much, you just know it. I think it's a process of getting proficient with the camera, and learning the business aspects of it while you're doing some practice portraits with family, etc. Then go into business, even if it's a sideline, so you can be successful.
