You know...it's not quite as bad as it seemed at first blush. These new stock photos make MP-45 look a little bit better. Honestly, the backpack isn't any worse than that of MP-21. Both stick out a fair bit. You might argue that MP-21 looks "cleaner" directly from the back (the both look messy from the side), but MP-45 just has an additional piece of the hood that doesn't really look out of place, given where everything else ends up, and neither design compromise is really all that accurate to the character model anyway. The fact that this gives MP-45 an Autobot "tramp stamp" is kind of amusing.
The feet on MP-45 are still inelegant, to say the least. The heels don't look quite as bad as in the first photos from Wonderfest, but they are obviously still a garbage dump for window kibble that couldn't hide elsewhere. What really irks me is how bad the insides of the feet look. MP-21 did a nice job of covering those up with the door panels for the most part, but MP-45 doesn't even try to hide that mess of plastic origami. I think Takara might have been better off trying to engineer the feet the same way as on MP-21 and just concentrating on working in the faux shrunken torso for robot mode instead of doing the whole transformation almost entirely from scratch.
