AI has a easy time learning concepts more than characters, bizarre I know, but has some trouble with overlays as it often misplaces it, be it shadows, fake screenshorts or viewfinders.
Also I fucked up and didn't paid attention so a long sleeve shirt got backed in, so add sleeveless to positive and sleeves to negative and it should help a bit.
And I got the 'universal' settings for character and concepts down, I think.
