Seems pretty much about right. With big thick outlines like that sometimes it's tough to get an exact scale, so for the most part I aimed for my edges to line up just short of the middle or inside the outline in some cases. Going by the outer black edge leaves a rather bubbly shape.
I'm still trying to figure out where the extra six pixels are coming from myself, but I'm at loss...and lunch break's over so this'll be my last post on the subject for a few hours.
Conflicting references, I'm also looking at many other images, especially those on the box art of the Hasegawa model kits, which are incredibly well done if you ask me. I chose to scale them to the size seen in those paintings, where they are quite prominent. I'm still fiddling with their shape
Fair enough. To be honest, IIRC those are running lights or something similar, and your design makes more
sense, but that wasn't quite the point of the conversation.

I disagree, as chief pointed out, it seems to match up quite well except for right at the base where the head will be. That's simply a matter of sanity, you can have either a flat bottomed nose (which doesn't seem to be the case) or an indentation that rises higher up. I chose the latter.
The indentation appears to be of different shape, with the nose rising earlier in the plan view; I don't trust overlay to effectively show that kind of difference myself (the plan view's heavy lines hide things), and looking at the pictures side by side it definitely seems to be different.
Well, first off, they're not lasers, (unless you're talking about a single bad case of commissioned animation by an outside company, which most macross fans choose to ignore)
But anyways, they're placeholders
Sue me.

I tend to regard the list of VF-1 weapons systems from the Robotech RPG as my reference. Besides, personal Discontinuity is all well and good, but expect it to bite you at some point.
That's a matter of conflicting references, while that plan view has one smaller than the other, many other pictures have them equally scaled
Fair enough. (I note the large VF-1 in flight line drawing I have does more or less exactly that.)
Artistic and functional choice for when it transforms to Battroid mode, as well as once again a case of conflicting references. In battroid mode, the forward "toe" protrudes further forward than the rear. If both were the same length in fighter mode, but with the rear having a sharper angle, it would have to stretch further back than the forward.
Fair enough, if getting this to transform properly is an objective. (And I admire your tenacity even if I slightly question your sanity for doing so, I tried to model a Cyclone from Mospeda/Robotech The Third once and discovered transformation was totally impossible).
