Some things that ocurred to me
***SPOILERS*** ***SPOILERS***
First, good job. Sets and lighting are really good, VFX are really good, the acting is good. I like how you made use of some resort or something to double for Vulcan. And good use of Chase Masterson! And I really like the blonde navigator.
Second, it's got some holes, or questions.
1. When Charlie (what's with the head bob?) goes through the Guardian, aren't those standing there supposed to be insulated from the time change? At least, that's how it happened in COTEOF.
2. When Charlie appears again after Chekov, Harriman, and Uhura return to the forbidden city, he appears the same age. Shouldn't he be twice the age?
3. What's with Uhura "remembering" the alternate timeline? She shouldn't remember a damned thing. Granted, Guinan was able to sense it ("Yesterday's Enterprise"), but her species is supposed to have mysterious abilities (which Dr. Soran never displayed, by the way). Uhura is just another Human. So all that makes no sense.
4. Why didn't J.G. Hertzler play "Martok?" Why didn't Garret Wang play "Kim?" Why did Chekov adopt another name? I mean they all are alive at that time period. Besides, it would have worked anyway given the story.
5. There's no way Starfleet would build a Constitution class ship, complete with period specific consoles, etc., at that time, especially to function soley as a flying museum. In the episode "Relics," Picard says there is a complete bridge of one on display at Starfleet, as a museum piece. So that doesn't wash. But I can see how you'd need it given the existence of the sets for Cawley's productions.
Anyway, that's all I have for now.
