vicen: Thank you for that above mod. It will certainly be quite nice! Now if only I could find a mod that improves the OC's and its expansions graphic wise I'd be set...not sure what to choose from that topic you listed...
From that list check out no.:
3 - to freely customize your character's looks in-game
12 - for Shader effects
14 - for tileset replacements (making the areas look a litle more like e.g. NWN2)
or 40 - alternatively, for a look more close to the original but with enhanced textures and a few different creature models
16 & 17 - for enhanced creature models
39 or 40 - for different GUI looks (there are more options, these are just my personal favorites)
Those are probably the most noticeable changes. The portrait selection is easy to enhance, just drop the according files in your "portraits" folder (or create one if there isn't one in the NWN directory). There are too many portraits and portrait packages to recommend any here though. Just do a Google or NWVault search and pick what you like.
Sadly, what I can't offer you is an overhaul of the OC's story-telling. IMO you'd really be better off looking for proper mod
ules. ;)
