First of all, I must praise you both for your attention to detail and stunning props. They look so authentic, I could be fooled into thinking they're real!
The cos-plays, essentially...are spectacular. Kirk wears that green-shirt so well. I love the expressions on both of your faces. Kirk looks daring and bold as (s)he should be, whereas Miss Spock looks quiet and reserved. Totally in character. So well done on that account.
As for the lighting, positioning of the camera, make up, etc. It's all fantastic. Wonderful job to you both. I am very impressed with what you've done here.
