I have 2 characters on the go, one is Jays Ramsay and another for game dev. I dont do organics and I can tell you it isnt easy...which is wierd because as Jay said we see humans all the time yet they are so damn difficult.
I havent finished Ramsay but I can say that is one of the best to get started with. Simple geo and not overly stuffed with with the hard stuff. Its a good simple tut which is easy to follow and well presented.
Good luck mate, you will fall down a bit but get back up and keep going.
