Some of those pics came out great! I haven't gotten a shot of mine yet that has come out looking half as good as yours. The 3rd shot down just needs to have the front wheels toed in a little more and lightened slightly so you can see the big rear meats and it would be perfect IMO.
Regarding the scoop, I think it looks good on your car. I still have the Feb 2000 Automobile magazine cover on my bookcase at work with the first shot of the competition coupe I had seen and it was the roof scoop that caught my eye more than anything.
I am curious how it attaches and I am assuming it is non-functional, so any concerns about it launching itself at high speeds when the pressure builds up or is the opening blocked off or the unit vented somehow?
Now if you put Knight Rider like LEDs flashing back and forth inside there, THAT would be over the line
