Hi Sylvia...when I first looked I thought the oof one on the right got in the way.
Then read you was concerned about the central position.
So I had a play and came up with cropping off most of the space on the right plus the bit on the left wit the dark stem in it.
Next create some more canvas at the top (about the same as there now) and stretched the colour there to fill it.
You could do more canvas on other sides if you think it needs it.
Good original image though with great atmosphere.
Will pm you to let you see it.
