I like the image but suggest cropping out the greenish ceiling tiles in both the lower left and right, as they don't seem to fit with the rest of the image
For me, the lines going in every direction are what make this image such a success. To remove the greenish ceiling areas being discussed would eliminate two important areas of the image. Those two areas seem to be lit by a different light source (perhaps fluorescent light), which results in the greenish look. One solution would be to change the color balance in those areas as Jean mentioned. Another solution is to convert the image to monochrome.
It's a very imagination shot and nicely done.
very well done
Very nice, +1 to Mike
