I also found that dialogue pictures work best if the blobbie is looking straight at you, except when there is a good reason to look some place else. Down if they're ashamed or up if they're exasperated for instance. In the earlier pictures I made, I wasn't very precise in these placements, so it felt like the blobbies were telling you things without really being interested in you. And even though this would probably be in character for most of the blobbies you'll encounter in Powargrid, it works counter to drawing the player into the story. So this had to change.
In all, the differences are subtle, until you look closely. Once you see it, the difference is glaringly obvious. Or perhaps I'm developing a rudimentary artist's eye ;). Some examples:
Happy gaming :)
