I bring to you an updated size reference for HTBD! I haven't started working on the twins but, that's kinda the general silhouette I have in mind :3
I probably should've tossed in a Ratchet silhouette but he stands just under Prowl's nose!
Edit: Hound is probably around the same size as Ratchet, maybe a teensy bit shorter. Something to keep in mind: The dragon's mech-alts optic height stays the same. Although Mirage and Prowl can obviously raise their helms higher, this is their usual "posture".
