Before I got and play Devil's Advocate - I do have to say that your skill is WAY beyond anything I could ever try.
That said, the perfectionist in me now comes out and I wanted to point out a couple things I noticed and think may improve the look... (my numbers correspond to the circles I put on the pic)
1. I think these are rectangular - not round. In looking at the reference pics you have provided as well as trying to pause my DVD, they really do not look round to me.
2. This looks a little smaller in the reference pics and a little closer to the top edge.
3. This also looks closer tot he top edge and even with the bottom of the center cap, not below it.
Now, that being said, what you have done is great and I think will work, but you did ask...
Thanks for indulging me.
