The problems with you not farming your jungle is that a) you're missing out on XP (which you can make up to some extent from ganks, but not enough) and b) you leave your jungle open for others to farm. In season 3, the jungle grants a lot more gold than it used to, so farming the jungle for a couple of items that increase the potency of your jungler counts for a lot.

That said, your jungling style is different than mine; I like Hecarim (farm until you hit 6 and have Wraith, then wreck things) and Shyvanna (counter-gank when necessary, otherwise just steal their jungle all day). I do play some of the champs you mentioned, but I imagine you have more experience on them.

I think that if what you're doing works.... keep doing it. When it doesn't work, identify your mistakes (LoL Replay can help with this) and theorize things you can do differently (hint: the answers usually involve wards, effective communication with your teammates, or something that is far more obvious than either of those two things). When what you are doing works, try to identify where you capitalized on your opponents' mistakes. I hope I'm helping. Good luck.
