Both nice images Leon
It is hard to really compare at this low res but I think your earlier image is actually a little better in some ways, it shows more variation in the colour and intensity in the nebula. The bright regions in this nebula are in fact a slightly different colour to the fainter outer extensions, because the area is so bright it should appear slightly whiter and brighter IMO, the more recent image has lost this variation a bit to me..?
Nice comparison though.
