Creating a new race based off another isnt hard at all, you'll wanna use the beginning of the CK tutorial from Bethesda, as it doesnt go into much depth at all, I honestly think its pretty weak but thats my opinion, anywhoser, you basically duplicate it and have to spend a lot of time figuring out which hairstyles/face types/skin color are which and adding the ones you want, and then you adjust all the stats, bonuses and the rest on the general race edit screen, most of it is pretty self explanatory. Once you get into custom racial abilites/powers etc is when it gets more complicated
