On that second comparison pic, the one with Han escorting the other ships, isn’t that the prototype design for the Pirate ship? judging by what materials the comic team had access to, I’m not surprised they got that design.
Yes, it does kind of look like it. But then again, that design was re-used for the Blockade Runner in the opening of ANH, so it’s probably just supposed to be one of those. There’s another ship visible underneath it which look very similar as well.
It was reused for the Blockade Runner, but the blockabde Runner had some modifications before being used (Mostly that cockpit, and I recall some of Cantwell and McQuarrie’s concept art had that antenna.)
So While I think it’s supposed to be based on the Tantive IV’s design (I don’t know if they were called CR-90’s yet, but I think the Tantive name was out there by this time), they didn’t seem to have the in film model as a reference to work with.
