Things that I like about the attached example Logos
Colt Logo: I like the use of the letter "C" in an abstract way. Consider using HQ in this fashion.
1980 Logo: I like the shape of the shield
Gardio Logo: I like this very much. Consider using dynamic shapes in the shield to show strength. Or using the H.Q. in a abstract way
The Company Logo: I like the detail in this logo. The shiny, shadowed shield is very cool!
Existing logo: I made this one myself use this for inspiration, but there is no need to stick to this design.
I like Black and Red. White and Yellow can be used as well, but just as accents.
