OK here it goes:

Note the number '4' in the above line? Remember it.

At this line, replace 'floor_height' with the number noted above.

Now delete the original 'floor' section of the code.
As far clouds are concerned, you'll have to use a 'sky_sphere'. Here's a sample
of code (I think this is Jeroen De Haan's code):
#include "colors.inc"
#declare VERSTERKING = 1.05 ;
#declare P_Cloud4 =
pigment {
wrinkles
turbulence 1 / 15
lambda 2.2
omega 0.707
color_map {
[0.20 SkyBlue * VERSTERKING ]
[0.50 White * VERSTERKING ]
[1.00 Gray70 * VERSTERKING ]
}
scale <0.5, 0.15, 1>
}
sky_sphere {
pigment {
gradient y
pigment_map {
[0.00 rgb <0.847, 0.749, 0.847> *1.2 ] // horizon
[0.10 SkyBlue*1.15 ] // horizon
[0.20 P_Cloud4 ]
}
}
}
