First off great energy! I can really feel the movement. I'm noticing a few things: In the second and third figures you're making the hands a bit on the small side. Go big with hands! It is a sign of confidence, makes them easier to draw, and reads really well. Another thing to always be mindful of is the silhouette of your figures, and how things overlap. In the first image, the characters left arm is in line with their ear. This is forming what is called a tangent. This kills the depth and makes it hard to understand what is going on. Consider moving that arm out a little bit so it is clear what the action is. Remember, you're the director! You can pose them in whatever way best tells your story. Great job!
