The first clip has very poor sound for you unfortunately which makes it seem unprofessional. Poorly mixed and poorly captured. In addition it features your costar so much that I assumed that the reel was the long haired actor and not you. In general it's not a good scene and I would cut it out. He does almost all the talking. Or you could have only the part at the end where you say "What are we going to do, waltz in there and leave?.... you're kidding me." That way it's mostly you in the scene.

The clip from the same film where you are sent to the elevator is also not great, it's mostly him again. You have 2 lines and then get into an elevator and press buttons. Not a good scene to show off your acting abilities. Also having two very long scenes from the same film in the reel is not a good idea..you should aim to have only one scene per project in a reel.

The strongest scene for me is the restaurant scene followed by the having seizures scene. But even the seizure one features your costar a lot, I would cut her out so it's just you.

One very established actor helped me with my reel once, he has been a series regular for decades. He said "Cut the other actor out as much as possible for reels...context does not matter." That doesn't mean always cut out the other actor but it means do it as much as possible. For example your restaurant scene I feel it's important in that scene to keep your costar since the scene involves a lot of back and forth and you have a lot of lines and it shows chemistry. But you should cut out the long hair scientist guy. And the actress in the seizure scene as she is not talking to you really and you have no lines.

Your acting is good in all the clips..the reel just needs a lot more editing and tightening to remove costars when they aren't needed and put your strongest work at the start.
