This is a nicer one than a previous effort a little while back (not that it wasnt ok),
i have taken a closer look at this one (i didnt look at the glob close enough the other day), if you pop it into photoshop and run the eyedropper tool accross the image you will find the red channel higher than the others fairly consistently accross the higher tones in the image, a slight drop in the top of the curve in the red channel could help this,(easily fixed)
the bottom end sky background is high at the blue end so a similar correction could be applied there.
apart from that its really good
i know the pentax is not of the same calibre as the new camera is ( it would be good to redo this with the new camera to see the difference).
