Directing actors is one of my best skills. However, I'm a beginner. I just discover this skill inside me. But I will tell my opinion about the acting in your reel.
0:05 - Excellent.
0:08 - Weak.
0:13 [girl] - Very good.
0:15 - Hard to analyze an actor with the face covered.
0:30 - People with guns breaking into a place, and faces without any emotion? You could have solved this by directing them to the use of the eyebrow, forcing it down would bring a nervous tone to the scene.
0:50 - Again this guy, he is really good.
but...
1:00 - here, his body position is not in accordance with what the environment is saying.
1:40 - The girl is excellent.
2:09 - I don't know your goal on this scene, but I think you should reduce the angle and distance from the camera. See how the actor is making a very good use of the muscles around his eyes. This is going unnoticed because you have positioned the camera as if shooting someone in your home, like unpretentiously. He also moves his head as well toning the words. If you shorten the distance, this move would increase the aggressiveness that he tried to transmit.
2:24: The actor makes an ironic expression very relevant to the scene. You have reduced the impact of this irony by framing him on the side. He needed a front framework to communicate the real meaning of what he is feeling in this situation. I think you directed the actor fine, but not framed what you asked him to do. His eyes, the curves of his cheeks, the movements on both sides of his mouth says a lot right on this moment.
2:46: I really don't understand this cloth covering the actor's face. We lost all of his work due this cover. And he seems to be very good hehe.
Just some opinions, dude. I love this work of directing actors. I am working with children right now, and learning A LOT with this experience. As I said before, I liked your reel.
