Hi Guys,
I played with Will Smith's face a little while ago. The ears in the screenie however are photoshopped, since I have no real knowledge of meshes to help stretch his ears horizontally.

I kinda gave up on him because the ears really would have made the character.
It's hard to tell from your character what changes to make because your screenie is not a console shot like these:


but I never publish a character once it is in Oblivion until I use the stock facegen sliders in the console mode, as seen above, to tone and shape the face. I NEVER use the Redguard race. I use mostly Imperial, no matter what race the celebrity is. My Will Smith is indeed Imperial as well as Snoop Dogg.

Yes, even TEAL'C was a new race from the Imperial race...
Early version:

Finished version:

Another tip; although it looks like you have an excellent looking SI Facegen render, I usually try different pics and save different renders. My photo of Will actually had a mustache and goatee, which helped him look older.
You need to get into the Oblivion console and tone and shape the face or they will never look realistic.
I have a question though, how were you able to export the face from SI Facegen? I ask because I see the "SI" on Will's forehead and I thought that unless you pay for the full version you could not export the face.
Yes you need Construction Set as well as DDS Converter. I make a new race from the Imperial race and rename the new race whatever I like, although it looks like I named Snoop's race as just Imperial. If you have any questions I am happy to help.
One more thing, I'm kinda busy with video work right now and my Windows XP died on me, so I think I may have lost my Will Smith character, but I may take a look for some saved data if you want and possibly make him available for download. Just wish I had those ears...
