Actually, I like the lighting the way it is. The floor in the shadow of the
large candle edges. The colour of the candle light still needs some yellow
or orange tingin to it though. And to make your candle more convincing (I
don't mind the shape or texture of the candle itself) you need a slight
waxy hollow in the top where the flame has started to melt the wax. (and a
better flame). Overall, you have a good scene composition, all you need is
a little tweaking on the lighting, and little more on some of the
texturing. For the background texturing of the box itself, the textures
you have been using may be fine, but you need to scale them down in size to
give the scene better overall scale perspective.

I haven't tried that yet...

You're probably right. Adding the extra blue light makes the floor less
dark and the candle less brown, but also makes the light it casts look
less yellowish. (And the dark brown wood probably doesn't help.)
Getting the balance of warm to cold colours is proving to be a challenge...

The flame is probably the easiest part to fix. (Which is why I haven't
bothered with it yet.)
A pool of molten wax would be good, but I'm really not sure how to
achieve it. (It took me hours to figure out the equation to make a
round-topped cylinder!)

The candle and box are supposed to be quite small...

Gail's material implies pigment is somewhat transparent to show the interior

I can't decide which marble fits the scene best...

Maybe this marble? (Now this is perhaps too bright... not much of a
pattern either.)

Last one!
Well, this certainly has a pattern to it... Looks a bit rubbish though.

You used an isosurface for it? That is something that would probably be
OK with a little CSG.
As for the pool, maybe a blob shape with a small scale value along the Y
axis?

After seeing your alternate marbles, I think I like this one the best :)
One quick note, it seems to me that the shadows on the ice below the
candle are too harsh - it looks completely solid (that *is* supposed to
be ice that it's on, and not stone, right?). I would make it completely
transparent, and fill it with a dense media instead (in fact, that's how
I would do the candle as well).
