Your right again this was done during an evening of experimentation with some new software. It was using just a single Jpeg again. I also blended a little colour around the edges. I like the photo but feel it is not  in focus, it was a quick snap I took and I think the point of focus actually falls on the wall to the right.

In a situation like this there just isn't much time to think but speed is of the importance! You could always crop the right hand wall out to re emphasise the point of interest? I think this is a real beautiful capture, well done
