books on sketching skliz...?

I read this book some time back:

“How to draw cars like a pro”

  • It does contain some basics regarding perspective generally and with refernce to automobile design also

Some more interesting works include “Art of Star wars” where in more futuristic wars are drawn and painted on paper. truly inspirational work.

Basic perspective principles have also been cleared up by author “Robert.W. Gill” (i guess I spelled it right…!) in his Sketching books and journals
