I like it. Substantially cleans up the look with the hood up as you're no longer looking down into the gaping hole in front of the radiator support. You could take it one step further and block the small openings now around the hood latch, but I don't think that's entirely necessary.
I've been wanting to fab the same sort of thing on my car for a while, but I was planning either on brushed aluminum or making a filler out of the same carbon fiber I made my intake lid with.
Your sticker picture isn't legible, but I've seen it before and know what it says.
