Brandon Teta:

I think you did a great job with the lip sync here as well as the expressions in general. I would love to have some indication of additional context to the story aside from the size of the main subject. I'd also look at making the movements move in more of an arc, like when he points his finger down or turns his head. Some extra follow through on the body and head throughout would help sell the actions more.

Nzuri Parker:

I like the overall acting, but the framing/composition of the scene feels a little too cramped. I would make the character in the foreground smaller and reveal some of their eyes. Also I might make the character who is talking look towards the foreground character. I think this would add subtle character interaction and it would justify the framing better.

Rhys Davey:

Looks good. A bit of polish and you'll have a nice reel piece.
Here are some notes for you.

EYELINE - If he's talking to the person in the foreground then his eyeline should be much closer to the camera. Right now it looks like he's looking at something 5 meters behind him.

I'M NOT - Jaw pops into the OH in NOT. Soften in the graph editor. Also hit the N shape better. Treat it like a bouncing ball, squash for N, stretch for O.

F50 - His head just cocks abruptly to the side. Grab that curve and give it a nice ease in and out. Do the same for the head turn at 90-100. It can still be fast but needs to be less jerky.

F108 - The hand moves at the same time as the head. I think if you offset the hand a few frames earlier it'll be a nice antic and also it'll brace for the extra weight as he leans to that side.

I like the motion and expressiveness for REAL. Good job!

F245 - Shift the shoulder lift a few frames later. Have it closer to the head move. Maybe 2 frames after the head tilt. Polish the curve because shoulders hang heavy.
