One nit pick I had with guy upon transforming him is how high the spoiler sits on his back. Then I looked at some pics that Sydneyy took and I think we might have the spoiler mistransformed in bot mode. I've only noticed Sydneyy do it this way, but I think it looks better if you fold down the spoiler and rotate it 180 degrees back up. The fact that the spoiler is made to rotate seems to indicate that this should be part of the transformation. Doing it this way also makes the spoiler not look like it's floating above his head and gives better overall proportions IMO. I wonder if Takara has this extra transformation step in their instructions for the crystal set. See pics:
That's the way he's packaged in the Sons of Cybertron crystal set. But I don't think it's correct. Like that, it's too low, and is almost completely hidden behind his shoulders. Rotating it around also pops it out of its socket, slightly. I'm pretty sure the only reason it's on a free-spinning joint the way it is is as an anti-breakage point. The little peg that keeps it aligned is too long, and works more as an anchor, than an alignment nub.
I actually like it sticking up higher. You could always see it in the animations but most of the toys had the spoiler sitting so low you can barely see it from the front.
Gah I didn't really think of it when I was taking pics! I am sure the wing is meant to be higher From behind I think he looks better with the wing set low though.
