In version 1.5 there is +60 new portraits divided in every race and sex (+5 to each)
In game there is four-eight portraits for each race in character creation and many other portraits used only for npcs. Am enlarged (and bit sharp edges) pictures of these npc to use as portraits of main character. Some of them are even better than main character portraits, anyway always good to have more choices.
There will be at least +20 new portraits, and maybe some new background story for characters.
