The problem is that image isn’t actually to scale. The difference between the ranger and the f150 (21 inches) appears the same as with the maverick (11 inches) When obviously it should be more pronounced with the f150. The heights are likewise off scale.
Rule number one when resizing something, lock that aspect ratio! Check the wheels on the Maverick, they’re compressed horizontally, making them oval shaped in the vertical and distorting the entire shape of the truck. Nice attempt though, just looks off to me.
