To be perfectly honest here, I am VERY DISAPPOINTED at the responses I see here to the OP's post.
The OP is asking for character enhancements, graphically.
The answer is, that of course there are huge advancements done to NWN graphics, character-wise. It is just that nobody has put them together into an easy-to-use-package. I am working on something along those lines.
Look here for what one can do with the game, graphically -

Here I show just how far one can go with NWN, graphically. I would hazard to guess it is probably possible to go even further - I am by no means an expert on such, nor do I have knowledge of all the available enhancements out there. Some of the work being done in the CC forums by CCers I think demonstrate this plainly.
As one can plainly see, one can approach NWN2 graphics in NWN with the right enhancements, without all the...other stuff that NWN2 brings with it.
I personally would suggest the use of Kamiryn's customizer, as it was mentioned earlier here in this thread. It allows for easy customization of your character's look in just about every aspect except for vfx's. For such, you will need other tools, unfortunately.
When I finally get my player package done, I will post it publically.
