thanks a lot VA, HB and AdW
I know my graphics are very amateurish but I try to be better.
The next graphic is the first that I made with GIMP. I tried to bring a light "wash effect" into the CAD (UG NX4) insignia.
I want to thank Viper Aviator for the 501st insignia link.
here is the CAD version of the 501st Austrian Outpost insignia
and here is the original insignia from VA's link
