Hi
Im new to pov too and it is a nice scene u have made.
i know about fotografy though and theres a couple of things that u can do.
u use two lightsouses but both are pointlight. u dont get any lightdepth
add an arealight.
i then chamged the two light to be dim and colored -it adds a moode to the
scene. Some might think thats wrong. Its a question of taste.
Never flood the scene in light. Dim the light and use PoVs amaging different
lightforms.
I added a texture and made the color translusient.
I think taht both the wood texture and the brass texture give interesting
result. -But the brass texture made rendering longer
Below is my sugestions -Thats all they are.
//code:

#include "colors.inc"
#include "arrays.inc"
// various (mostly layered) wood textures
// T_Wood1 - T_Wood35
#include "woods.inc"
// several different gold colors, finishes and textures
#include "golds.inc"

// various metal colors, finishes and textures
// brass, copper, chrome, silver
#include "metals.inc"


camera {
     location <9,7,10>
     look_at <0,-5,0>
}

light_source { <-10,10,20> color Yellow*.3}
light_source { <10,10,10> color Red*.3}



  // An area light (creates soft shadows)
// WARNING: This special light can significantly slow down rendering times!
light_source {
  0*x                 // light's position (translated below)
  color rgb 1.0*1.6       // light's color
  area_light
  <8, 0, 0> <0, 0, 8> // lights spread out across this distance (x * z)
  4, 4                // total number of lights in grid (4x*4z = 16 lights)
  adaptive 0          // 0,1,2,3...
  jitter              // adds random softening of light
  circular            // make the shape of the light circular
  orient              // orient light
  translate <40, 80, -40>   // <x y z> position of light
}
