Fricking cool, and really nice work...but I don't think it's really that accurate, to be honest.There's not such a big difference between WFC and FOC Prime, the Michael Bay Prime looks pretty small (the movie bots are among the largest ones), and I'm pretty sure Prime Prime (even with all the mass shifting going on) is not supposed to be that incredibly large..I mean, I don't blame you. There's tons of places where supposed heights are made up for official factsheets, and in the cartoons and comics sizes are depicted pretty randomly. In Animated, for example, there's a shot where Prime is going up on an elevator in Sumdac Tower and he's, while later on he's really not that much larger than the G1 version would be.tl;dr: TFs' sizes are often exaggerated, inaccurate, and I wouldn't really bother trying to come up with a cross-incarnations scale chart.But it's still really nice to see all the different designs lined up
