i'd have said by looking that the Arctic shadow has a silver body probably just an ally tube left bare, a wing of yellow polar bear some crystal flash then black goat on top of this, some slim grizzly hen feathers for the sides and a sparse hackle of blue guinea fowl and a black head to finish.
The gaspe looks like a silver braid body, a wing made up of orange arctic fox with black arctic fox on top then some peacock hearl and crystal flash, a set of JC eyes, a black head and finished.
Obviously you would need to take the proportions off the photos.
For the record I wouldn't say these flies are anything special and would seriously doubt they would suddenly increase your catches.
