Critiqued in line.
This is a bit confusing. How do you take normal falling damage before you fall to the ground? Also the DC of the climb check seems high.
How does say a Human climb a gnome? I mean the image I get is Hilarious. But this should probably have at least a size requirement of equal to your own.
What exactly is the normal climb DC of someone's skin? Perhaps eliminate the touch attack, make it an Climb check vs their AC?
Again the climb DC seems really high. And also again your taking damage before you hit the ground?
So an inferior and limited version of spring attack?
Note sure this is really likely to come up often enough that the maneuver is really worth having? I don't think that this has every come up in any game I have played.
For a third level stance this seems incredibly weak.
Ok. Again. Human uses this on a gnome. Hilarity ensues. Also again, I might suggest making this a single "attack" Climb vs AC, or even AC plus a small bonus or something?
Again with the really high DC and also the taking damage before you actually hit ground.
This I like.
I see no reason that as a 5th level Stance for this to be limited to half your speed.
Greater High Critical Strike
Bulldog Tooth (Strike)
Level: 5
Initiation Action: 1 standard action
Prerequisites: 2 Bulldog Tooth Maneuvers
Beginning on the ground, you grab a handhold on the enemy and then swing up to strike somewhere particularly vulnerable that it thought was out of your reach. First make a touch attack to find the handhold, then the real attack against which the enemy is flat-footed. On the real attack, your critical threat range is doubled (this stacks with other crit-improving effects such as keen) and your critical multiplier is increased by 1. Afterward, you may choose to either drop to the ground or remain climbing the enemy.[/quote]
See all the similar ones about.
This doesn't actually do anything. The limb is grappled... so you are incredibly more vulnerable to the rest of the body, and at best, have limited the use of that one limb. Not a good trade off.
Not bad. I kinda like this. Though since you are sharing a creatures square when climbing on it, I am pretty sure that you are always going to technically be within reach of their eyes from a RAW perspective.

Esophagus Climb
Bulldog Tooth (Counter)
Level: 7
Initiation Action: 1 immediate action
Prerequisites: 1 Bulldog Tooth Maneuver
When an enemy swallows you whole, you climb back up the esophagus into the back of the mouth. This requires a dc 30 climb check. In the back of the mouth you are immune to bite attacks, but automatically fail saves against the mouth's breath weapon (if any). Furthermore, the enemy is flat-footed and denied any armor or natural armor bonus, and all successful hits are critical. On the creatures subsequent turns, it can try to swallow you (its str vs your climb) or spit you out (its str vs your str) as a swift action.[/quote]
Not sure that an immediate action counter should give you multiple rounds of benefit like this.
Knowledge Nature? Seems like Heal would be far more appropriate.
Again I think Heal would be a more appropriate skill to understanding the inner workings of a living being. Also size issues. Human vs. Gnome and all.
Really clunky wording. Not sure how exactly to fix that due to the way multipliers work in DnD Math, but this wording is kinda off. Say I crit for 20, do I then add 60 more? That would be how I read this, though I think, and I could be wrong that what you were saying it to triple the damage you would have done, which means it would be 60 total.
Overall a lot of this school seems incredibly situational. And there are a few things I think you should change. But good start.
