Stepping up my lighting for lego photography

I find lot of fun shooting pictures of toys, especially Lego bricks.

To light my scenes, I’m using one or more of those elements :

  • Natural light
  • Canon 430 EX II
  • Small torch LEDs torch

Here is a shot I took yesterday with a Canon 430 EX II and basic light bounces (sheets of paper) :

I like it but I would like to find a result more “realistic” and less plastic and colored. Since a picture is worth a thousand words, here is a website of a photographer who is, to my opinion, filled with talent…

  • I’m looking for ways to improve my lighting and my overall composition.
  • Is it necessary to have expensive equipment to do such stuff ?
  • Can those results be obtained only by editing the pictures ?
