Composition

It seems I have a tendency to run my compositions off the page. It's something I really am intrigued with. Although it makes it more contemporary a style I think it works for me, since my subject is so traditional.

I feel like there is a completeness to it. Although when trying to create a traditional still life, I find working with empty space difficult not sure what to do with it.

I also find, I'm still running it off the page.

                     These last few examples have been me painfully conscious and trying 
                                                             NOT to use the sides.
                                         

So the question is, which ones work better?
