Nice work Marcus, more detail particularly in the medium dark toned areas of the image and just a more overall illumination to give it more punch.
I think mike is the only one that gets too worried about the grain in an image..... Left over from film days I think,
My only query is when you put them side by side ( old and new) there is an area far left centre which has a different overall illumination, as a stand alone you probably wouldn't notice but side by side it suggests some reasonably aggressive masking. Minor point though as it is a pleasing image to look at.
