Thanks for the comments
I'm always open for ideas hence my posting in the critique section
The branch has now gone and it makes the image better overall.
Thanks for the crop comment Roger. However I agree that the bottom area is needed for balance, I like to use white (or in this case black) space to give areas of space in the image and also for our imagination to have a place to wander. There are small area's of texture and light down there, It doesn't show to well on the jpeg, but does make a difference in the printed image.
Thank you all for your comments, I have this morning made a number of 11x11 prints of this and am extremely happy with the output. It's looking great. The critique and comments of talented individuals makes a difference to my confidence.
