Can someone suggest me a good race overhaul?

I know the following mods tweak the races:

- Borealis
- Skyre races

Do you have other alternatives?

Thanks for help

http://skyrim.nexusmods.com/mods/18911//? by SushiSquid is one of my personal favorites, although it's not a huge overhaul like the others. You could probably use it in conjunction with the others, though; I personally love the changes he makes to the racial powers.
