The only real difference in these, that I can see is the focus is a bit crisper in the manual and the lighting is different, because auto likes it brighter. I tend to go for a bit darker shot, just my taste...
Mind you, I didn't touch the lens between shots..... The focus is due to the camera taking a slower shot in Auto. So it's not a focus issue due to me not focusing the lens correctly, rather its blue induced from the shake of the camera when I clicked the shutter button.
The editing in Lightroom was very minimal.
