I am new to blender compositing and am trying to make the first picture look like the second one ( which is an imgur because it is too heavy. So my initial thoughts were: the 1st picture is too contrasted and over exposed and i need to make the whites a bit more yellowish without changing the grey floor. However i can't seem to dissociate the different elements of my scene !
Any help would be appreciated. Thanks guys, have a nice day
