Hi ya Merideth ...
Welcome to the FSM community modeling forum(s).
I think you will find that we are a very diverse and friendly group of scale modelers from all corners of the world.
It sounds to me like your interest as a graphic designer in things of the '40's will mesh well with scale modeling.
Your choice of the P-38 Lighnting is a good one ... in my humble opinion ... one of the greatest aircraft of the century. My uncle on my fathers side flew the P-38 Lightning from a base south of London England in '42 - '43, ... good luck with your project.
