Control and skeleton linking for character

I spent to day developing my characters skeleton and controls, it  went very well and I had no problems, I have enjoyed working on this part of my model this time around, I would say this is because I took the time to watch the tutorial videos to give me a better understanding where as before I skipped parts due to impatience with the videos which later resulted in my test characters joints not turning out correct. I have managed to focus and work on my character properly step by step thanks to my tutor Matts guides, I don't really know what I would do with out the videos because i still feel that i do not have a full grapes of them and need practice, that is why I believe the videos are helping me improve more and more overtime I use Maya because I am begging understand its tools and functions the more I work with the package and its display. Every thing went well building the skeleton and controls, the on the problem is my understanding when to freeze my character in parts because I always make the mistake of freezing a group when I am not supposed to which resulted in me having to redo group every party of my characters skeleton, in the future I must not group everything stage by stage and not at the very end because it confuses with characters joints and orients.
