I can see well enough, thanks

I meant what is missing is a focal point, something you want to show or tell us. If you work on a picture, compare it with a text you're writing: what do I want to show? What is at its centre? Try to think of your scene and see whether there is something...
I'll make an example. Let's say you work on a mountain scene. Think...what shall it look like? Will there be snow? Trees? Which perspective is the most expressive one? etc.
Well...I sound arty-farty but I thought this might help you.
