I always get a chuckle out of this piece of layout artwork featuring She-Ra from the season one episode "Three Courageous Hearts". This piece of artwork shows the moment She-Ra leaps from the window of Castle Mystacor and into the throne room. However, out of context this illustration appears to show She-Ra flying! I am often more a fan of the layout artwork than the finished pencil art for animation, because you see a great deal more freedom in the illustrative work.
