Does your console look like pic1 after you turn on the game? (you can disable full screen to see it or alt+tab ), if there are some errors at the bottom/top let me know.
If it doesn't it means you didn't install it correctly. Or you didn't put /conquestrandportraits in /mods folder
1. install not so random images (improved random is currently incompatible), to do that put /conquestrandportraits folder in your /mods folder and copy contents of /conquest folder into game folder
2. install tweaks, to do that copy contents of /conquest folder into game folder
