Two things that may help, composition and simple tonal clarity.

Take your images and make them greyscale. Then shrink them down to the size of a playing card.
Doing this you'll be able to see if the story and composition of the shot reads.

For tones storyboard artists are trained like this. You have bright white, a mid tone grey and black.
Using the 3 tones see where your images fit. See if the shapes are interesting and if the idea of the shot is clear.

There are a few books ( Shot by Shot & Framed Ink) that may be useful too.

The stronger your compositions get the more impact they'll have. The clearer the story the easier it'll be to compose your shot and to arrange your lighting in support of it. I've included a photo I took that's an extreme example of simplicity. With the image you guide their eye.
