Replacements for the Windows keys would be perfect... as Microsoft has been likened to an
Evil Empire ...
Dude, those are perfect!
The Imperial logo is a little bit off. Most importantly, within the innermost circle, the white and black segments should be the same size.
Here is a close-up photo of an original helmet from the Star Wars movies, taken by a fan during an exhibit. I think that it is from a
Death Star gunner's helmet.
Note that the decal has been cut on the right side for better fit on the spherical surface of the helmet.
The proportions are quite easy to see, however.
