Lovely filter adding a nostalgic mood and feel to your picture Jack. Crossed colors are very nice and softnened by the mood. Vignetting and presentation adding a lot.
It sounds complex, what you are doing, only because I am not familiar with that software myself. This gray day though looks a lot like how it looks here, now.. and how it will later when the fog descends. A very moody and interesting [with your different processes] series of shots.
