You say a lot of things like, "This person is detail-oriented... this guys a big picture thinker...etc...".
Rocky has a point. It is better to describe only what you see and avoid drawing general conclusions like "this guy is a big picture thinker", because otherwise we have to rely on that you have made the correct interpretations of what you can observe. Try to be as concrete as possible. In exactly what way is he a big picture thinker? Can you give us any concrete examples of situations in which you think that this "picture thinking" reveals itself? And so on.
