I see it, the funky shadows.
@doulos4iesou (Greg McKim) , @artifact , with reference to @blanchsb problem with the clash of the engine enclosure, I think the engine enclosure is actually slightly narrow at the cab end or at least the same, doesn’t get wider, I think I remember @theluthier mention it in one of the live streams.
This image shows a good view, lens distortion probably not helping but the pistons and the loading arm will be as straight as a die, with that as reference it looks fairly straight, maybe narrower as it rounds over the top.

@dostovel with reference to the battery box the scale may need to be checked, remember the reference image has been scaled according to other sources. Also I think they need to be moved back an inch or two in the Y axis.
And I noticed an angle to one side of your boxes, I cant seem to line up the rear fenders with it. Looking at the image below the angle maybe the other side (1), also they need to move forward in the X axis for the step to line up better with the cab (2) and the rear (right in this image) side needs more of a curve (3). This would help me with the fenders as well as @blanchsb with the loader arm.
