Um, nope.  The satin chrome of the barrel and thimble isn't quite right, 
but my thoughts would be more work on the lighting.  The color of the 
micrometer frame, depends on maker.  No name on it, I'll assume chinese. 
  My Starrets, the frame was a gloss black when they were new. now a 
beat up gloss black in places.  the vernier for the ten thousandths is 
correct as shown.

The satin chrome will vary depending on manufacturer and age, I have 
older Starrett and Lufkin with the chrome polished to a high shine, from 
use.  The spindle is always ground and polished, tool steel, not 
stainless steel.  The carbide anvils always have a grayish appearance, 
this from the manufacturing process, not highly reflective.

The only thing I see that looks really odd is the sharp, dark shadow 
where the thimble meets the barrel, I've never seen that even with new 
micrometers.  (Diffusion from the satin chrome, probably?)

Otherwise, beautiful job.

Thank you.
Your comments are right on, apparently there's no fooling you. The
thimble/barrel shadow is my lack of a global illumination solution. The frame is
suposed to be a slight blue colour.

I think that the balance is looking ok. You could try stretching the normals
along the long axis.

Go for it :)

It has been so long since I used a vernier that I should keep quiet ;)
