Holy cow, B, I didn't know you had anything like this on the bench. As a former Cal-Look bug owner and long time enthusiast, I can tell you that you nailed it. Everything looks just right! The engine cover trick is called a decklid stand-off.
Have you heard of Fink's Garage? He and Hideo Motohashi on Facebook have some great wheels that are much better than the ones in the Model A kits.
I have yet to build a bug ( in scale ) because I'm such a perfectionist I don't know if I'd be happy. However, yours is excellent!
