Thanks for the comments Simon & vtecsilver very much appreciated. Whilst I have photo shop and had it for a few years still very much finding my way around it, so comments about raising shadows and boosting contrast and shadows are much appreciated.
Regarding dust spots, I do as a rule take them out 1st however missed them this time around. I really must get around to having the sensor cleaned, maybe now the winter is here and the camera will not be used much, now is the time to get it sorted.
