Andrew, I can’t remember if I’ve mentioned this to you or not (I probably have) but you should seriously get a copy of Jason Osipa’s book Stop Staring. Even though it’s written for Maya, it’s easy to follow it in any program. The great thing about the book is that it teaches principles - the why’s of the process. And while it’s all about head modelling, the principles illustrated in that book apply across the board in all facets of organic modelling.
When it comes to modelling, I think that understanding the principles is far more important that knowing what tools to use and what buttons to press. Because once you know the principles you can figure out the rest on your own.
Trust me, once you know modelling theory, you’ll NEVER EVER need a tutorial on modelling again - because you will be able to tackle any modelling situation you encounter. Seriously.
Check out the Modelling forum here on CGTalk and read about things like edge loops and organic modelling.
In all honesty, I’ve only done about 3 or 4 tutorials EVER. I decided long ago to rather concentrate on learning theory behind methods, as opposed to pure methods themselves. Learning theory enables you to develop your own methods while applying concepts that work because they follow fundamental rules.
Don’t despair 
Be pro-active in your learning. Take the plunge and read some theory - and by theory I don’t mean boring math. I mean the concepts and fundamentals behind successful modelling. Once you know why things work, you’ll be free to let your imagination run wild since you’ll be able to do whatever you want. I promise 
Having said that, I really think it’s time I get some sleep.
