I can see what John is getting at with the suggestion of using flash, but I think on-camera, even hot shoe mounted, flash may not help increase texture as, at these distances, it is effectively along the lens axis, so would just add more 'flat' lighting to that already evident in 1, 2 and 4.
To be effective, I feel it would need to be significantly off lens axis and if you imagine an off-camera flash held just out of shot somewhere around the periphery, to cast shadows across the textures present, I fear light fall-off would be very evident due to the relative distances of light source to texture closest to flash vs that say, 3 x more distant, on the opposite side.
I guess the answer would be a powerful flash, well off axis, behind the camera and (probably) above and door.
However, I haven't tried either - I'm just thinking through the likely result - and probably not helping much with negative thoughts!
