Ed's left hand is perfect. All fingers are naturally curled and relaxed. I can't see Ed's right hand tho, because of the camera angle. If I can see your right hand pose, maybe we can find the root of the problem. Please change the camera angle Ed.
Tom's left hand is messed up. I often think fingers are like soldiers. Veteran soldiers are disciplined, they only move when the general told them to. They keep cool and won't be affected by their ally's movement. While untrained, rookie soldiers move by themselves. They are stiff, confused and follow other soldiers without permission. Please practice scale without your right hand (no pluck) and left thumb (no hold), use only 4 left hand fingers, move slowly, touch the guitar board gently, fret by fret, string by string. That's what I often did when I my hands are stiff.
Hope that helps.
