I'm replying to this post to avoid unwanted indents, I see your other

Agreed, but the top right and bottom left are reserved for the
artist and title, so I'm not too worried.

yes, it's difficult to get that right, because of the way the landscape
is done using a pigment function to generate a height field (see attachment)
the fine grain noise in the landscape falls to zero along with the rest of
the function as it approaches the valley floor.
I guess I could add the noise rather than multiplying it in

The rails are blobs of cylinders that run from one end of the rail
to the other, pinned around a circle at the far end and around the
rail cross section at the near, this is the only feature of the
track/neck that doesn't make use of the spline function, and being
that way they definately touch the sleepers at the start and definately
hang well above the frets at the end. I guess they probably are starting
to take off as you indicated, but I think that's just part of the
picture.

I like the clamps, (see attachment :-)
close up they are very physical objects. The rust texture isn't mine.
I'd be sad to loose them.

yeah, I didn't want to put them on the nearest sleepers because then
they'd seem to just stop, and by the 4th sleepers out it's too far
towards being a guitar - compromise rather than artistic license.

Yes you are right. In fact the problem is probably that they go black
at all. A rich dark brown wood would be better.
