actually that comparison is misleading. The 1d has a squat, box shaped head head while the 1s head is elongated. a 1/48 could use something like the pop-out necks on the vf-0 line or a slightly compromised 1d head like in the 1d customs...
I realize that a toy isn't going to 100% match the line art, especially the old stuff, but the head placement is really off on the 1/60 ver. 2.0. Out of all of the transforming vf-1 toys, it's the only toy to put the head up so high
