On the nitpick front I noticed:
When Spock got smacked in the head he had red blood. (He seemed to be bleeding from the mouth).
When Spock beamed down to Delta Vega it looked like the same new swirly transporter effect from the movie. I can understand that they changed the look of the transporter for the film but transporter effects usually seem different from species to species so I don't know why look of the transporter from a 24th century Romulan ship would look the same as the transporter effect from a 23rd century federation ship.
But those are really small nitpicks. Not a bad mini-series as a whole, even if they did crowbar in a V'ger cameo.
