This is a fine memorial, and is totally fitting.
I truly hate to be a prophet of doom, but I would wager a good dinner that the feature of the climbing Hawks will not survive the summer; we live in an age of pi$$ed-up chavs to whom this would be irresistible in the small hours.
It pains me to say that such memorials, in future, should be designed with this in mind - these are the times that we live in. Couple this with the metal theft epidemic, which is not only confined to the UK; I recently saw a WW2 American memorial in the Saarland of Germany which had several large bronze plaques crudely ripped out & stolen.
I may be too much of a liberal, but I would have such people skinned alive & burned at the stake.
