Best is a matter of opinion, a lot of people myself included use xenius race compilation. As for making them look good if your not capable of creating a character whose looks you like on your own you could allways find a saved game for your chosen character race and go with that. For Sexy walks I use Pretty Woman in combination with Womans Move run animation I should be more clear. Some companion/race mods require specific body mods, which in turn require head mods, complection mods, etc. I don't mind using body/head/face mods that change my character or every NPC in Oblivion, I just don't want to a land of yellow 'wtf.' I therefore assume that other members of this forum have, by trial and error, arrived at a balanced, non-conflicting combination of body/head mods. The xenius race requires Roberts Male Body and HG Eye Candy Body which in turn requires Ozmo's High Rez Skin Textures for HGEC. How does those body mods affect the player or the NPCs of the game? Your going to find that most mods that deal with the player character and NPC's either require or recommend HGEC and Roberts Male body. Ozmo's High Rez Skin Textures are not really a requirement but rather a strong recomendation. I personaly do not use them. xenius race's do not affect NPC's at all, unless you install a companion that was made to be one of Xens beautiful races. His races are for the most part player only unles as I mentioned you make or download a companion mod built on his races. In fact off the top of my head I really cannot think of a custom race that would effect Vanilla NPC's. Cosmetic Packs such as Beautiful People are worth looking into but be sure that your down loading a mod that is currently supported or you could run into trouble. I personaly use Modular Beautiful People 2CH, the only draw back to that mod I feel is that it also adds a whole lot of races that no one likes. Its Major strengths iare the few truly beautiful races that it contains and that it has nearly every single hair style and eye texture ever made. as for companions if you look into vilja and viconia I think you should be safe with installing in combination with other mods, stroker wolf and the argonian whose I cant remember are also good choices.
