There's a LOT of thought going on behind their eyes in this. Starscream is particularly scary, and Megatron looks so young and tired! (those dull eyes! ) It's unnerving to see him taller than Megatron -- a real power-shift.
Thank you. Starscream surely is not taller than Megatron, they are sitting, not standing. And seeker is definitely sitting on Allmighty's knees Here Starscream's head is also higher than Megatron's.
