I own several of these excellent guides to improve my building skills in whatever I work on (cars, aircraft, sci-fi).
Filled with tons of pictures and explanations (Italian yes, but with English translation) you can read any section of these brilliant how-to's and become a better modeler with your very next project. The work shown in these books is the quality usually reserved for the Best in Show contest winners...but then they EXPLAIN and SHOW how any modeler can do it
I improve my skills by learning from talented builders: some explain their tips you at the model contests...these books give you the ability to learn the intricate details of those tips in your own home, anytime you want.
Build your confidence with one of these Guides; and you will find yourself amazed at how it will upgrade your modeling game
