I can't say how much I'm pleased to see your's Enterprise version. She is beautifull.
If I had to vote for one to be used on the new film my vote will be yours.
The original Enterprise from TOS series was made to be a model. Not much detailed because of the costs and easier to be made on wood and plastic. After that Enterprise-D was a little plastic too.
If we look at Enterprises B and E we can see on other hand starships more detailed than the first 3 starships.
But in other hand if we take the NX-01 Enterprise design... she is a lot more rich on details.
May be they, the producers, will go on this way. Just thinking about. But, honestly, I'll prefer your work. You added details but you keep this old beautifull lady elegant and gracious.
Well done.
