You CAN do your own portraits, just like Baldur's Gate.

Best thing of all, you can keep adding portraits to the same file, so you can have virtually infinite portraits.
I used my Dragon Age character which I spent hours on, trying to have it look like me as much as possible, & pasted it over the Tavern background. Personally, I think it worked rather well.

EDIT: The forum automatically crops the right hand side of the image, so I removed the original image & posted just the sidebar. Here's the link for the full screenshot:
