Sounds pretty good! Amber ales can be fairly high on the hops character, as long as your grist provides a solid malt backbone and a pronounced caramel character.
In fact, your caramel character is going to be somewhat lacking for American Amber Ale with only a quarter pound of 20L crystal. I'd either up that to at least three quarters of a pound or use a half-pound of a darker, say 60L, crystal.
As it stands, I agree the recipe sounds tasty. Just needs a tweak to bring it into AAA territory.
