Scale is accurate , plenty of room for 4+ in cockpit if I were to have done the interior .
I stand corrected! (and I'm happy about that). For whatever reason, it might be the angle, it looked smaller to me in those first few photos. Your recent set definitely set the scale better for it.
I love the neck adition! I hope that you at least build in a compartment into the body which can be opened and a few figures placed inside. It's a real shame not to have some playability with the inside of this monster!
I would also customize a couple tie pilots into drivers if I were you!
If you didn't use any kind of heat gun to bend the plastic then I am uber impressed with the bends you've achieved. I can't wait to see more of this monstrosity!
