Need some fine tuning ideas for this image, particularly with reference to
the soil. I am currently using an isosurface but it really doesn't look
right, is this something I might be able to fix with texturing or is there a
better way to generate it? I am yet to texture the walls and I think the
table could do with being less reflective.

The tree was generated using Gilles Trans Maketree and the rest was done by
hand except the screen, which was borrowed from a website I found, (sorry if
it was yours and I wasn't supposed to use it!) to which I added an image map
of a chinese painting.

Actualy I like the soil in your pot, but really it would be mostly covered
by moss...  Try using a layered texture with something like this after your
current dirt texture:

texture{
    pigment{slope{y} turbulence .7
        pigment_map{
            [0 rgbt 1]
            [.5 rgbt 1]
            [.5 bozo scale .05 turbulence .523
                color_map{
                    [0 rgb<119/255,175/255,143/255>*.9]
                    [.98 rgb<.85,.95,.02>*.9]
                    [1 rgb<22/255,57/255,0>]
                }
            ]
            [1 bozo scale .05 turbulence .523
                color_map{
                    [0 rgb<.85,.95,.02>*.9]
                    [.5 rgb<40/255,77/255,16/255>]
                    [1 rgb<119/255,175/255,143/255>*.9]
                }
            ]
        }
    }
    normal{slope{y} turbulence .7
        normal_map{
            [0 bumps 0]
            [.5 bumps 0]
            [.5 granite .5 turbulence .42 scale .15]
            [1 granite .65 turbulence .42 scale .15]
        }
    }
}

It might need some tweaking for your scene though.

You might try a "finer grained" texture for the soil... more small bumps in
it.  Vary the colors a bit too... most soils won't have one flat color to
them.  You might even think about putting some small clumps of grass or moss
in it.

The table seems too dark to me... the color seems out of place in the scene
with the screen and floor being much lighter in color.

Leaves and screen look good... I like the shadow on the back wall from the
screen, nicely done.

Thanks, I took a bit of time over the textures on the tree and to get the
screen right, but the table and floor are just standard wood textures,
T_Wood9 on the table I think, with a different finish. I'll add a few more
bits and post it again in a few days, I don't think it's a bad effort since
I've only been ratracing since I downloaded POVRAY about 8 weeks ago and
was on holiday for three of them!

Amazing job, especially for only having been at this for a few weeks!

You might want to create "boards" for the floor, but simply creating several
boxes (in a while loop), and translating the texture by some random amount.
...Or maybe there's a way to do that within the texture itself...

I've only been at this for about a year now as well.  I remember how
exciting it was back in the "early days"...  *sigh*

I would say that the soil is much too smooth. Add some more small-scaled 
noise to the isosurface and it should look better. As far as texturing 
goes, it should probably be a little lighter in color (unless it's 
either naturally dark soil, or it's soaking wet) and some color 
variation would be good. You want a mix of browns and grays. Try looking 
at some real soil and you'll see what I mean.
