in 0.90 you should be able to see all the Artwork, but you’ll have to play it multiple times of course.
4 is the Barakai Interior Diagram
The Nasir/Yoshi CG has two versions, depending on if you choose the kinky choice at the end, so there are two entries in the Artwork gallery, one that says Kink and one that says No Kink.
(SPOILER)
The last two are the new “bad” endings for Yoshi. The first could happen at the beginning chapter if you make the “wrong” choices. The final one could happen during Kol’s route if you avoid romancing him and then make the wrong choices during the confrontation with Nasir and Kol in the galley.
We are working on the CG artwork for Doc now, so it will be in the next update!
