Much as I'm not satisfied with Dinah there, I definitely think she's an improvement for exactly those reasons. Of Like Minds was my least favorite until I saw Sensei & Student.
Boobs with Ed Benes are just par for the course since you'll get a lot more in the interiors anyway. And though I hate the top he's shoved Babs into on that cover, my major issue with the cover of Of Like Minds (and every single other cover Benes did) is how visually dull it is. Nothing happening whatsoever, just the three of them posing for the most embarrassing family portrait ever. I'm not sure if The Battle Within is worse or not, because they are doing something now and it still looks dull (and oh my god i hate that picture of Helena).
