My anachronistic Lion design with drawing

This is another version of my anachronistic Lion design, dating from the 1980's. I have a photograph of my original pencil drawing that I had to enhance, which darkened it considerably:

I thought that this was the best way to show the sort of look I liked "back when". For some reason, the protection is adequate and the roll period is quite nice at 15.9 seconds. The design turned out pretty well in Springsharp 3.0b Beta:
