That looks great! Your macro seems to do a better job on certain parts 
of the image such as:
1) The line at the top of the propeller blade
2) The inside of the propeller blade
3) The handle on the door

..but I'm guessing that this may be do with the angle at which the 
camera is viewing the object?

I've now uploaded the POV source files that I used to create the 
helicopter colouring page. See link below:

I think for certain types of shape, your macro may render a better 
result. I created a colouring page of a Star Wars Battle Droid using the 
  same technique, but the PovEdge macro picked up to many edges on the 
battle droids head. This can be seen on the following link:

If I upload the source of the battle droid image would you mind trying 
your technique with that model?
