tying first dry fly - need guidance

[Byron haugh]

Steven,
How would one interpret this quote from Valla's book?:

"Marinaro wrote compellingly that a dry fly's wing was of paramount importance in pattern design: "for the wing, its height and breadth and flatness, is the most important part of a floating dun!"

Here's my attempt at a thorax dun style using turkey flats. Probably not the best example though.
