Nope looks pretty much dead on to me. See [0] for the real ISS vs [1] for the box art. The relative scales are a little off due to the available pieces (the larger radiators are pretty big compared to the solar arrays).
Ah, I stand corrected, thank you. My mental image of the ISS was somewhat distorted, it seems. And I had no idea the main solar panels could pivot to align with the large radiators!
I didn't know the smaller radiators existed at all TBH. Makes sense though since they're on the same structure as the solar panels it would ensure those are basically always in the shade more or less since the solar panels will want to align perpendicular to the sun. As for the solar panels they can rotate each individually around it's long axis and the group of 4 at each end as a unit around the long axis of the truss.
