We could just max Concentration and Intimidate, reducing Sense Motive and Tumble to 24 each. If you don't want to bump Climb, that's ok. I personally wouldn't make Swim better than Climb.
So you're proposing:
Skills Ranks: Climb 32, Concentration 30, Intimidate 40, Knowledge (nature) 32, Knowledge (the planes) 32, Hide 32, Listen 32, Move Silently 32, Sense Motive 24, Search 32, Spot 32, Swim 32, Survival 32, Tumble 24, Use Magic Device 32
The Hawk Lord, by contrast has:
Skills Ranks: Balance 0, Bluff 40, Concentration 20, Diplomacy 40, Disguise 0, Knowledge (nature) 20, Knowledge (the planes) 20, Hide 40, Intimidate 0, Jump 0, Listen 40, Move Silently 40, Sense Motive 40, Search 40, Spot 40, Survival 20, Tumble 40, Use Magic Device 40
I don't like the idea of giving the Lizard so much higher Concentration, Knowledge and Survival skills than the Hawk Lord.
How about so:
Skills Ranks: Climb 24, Concentration 20, Intimidate 40, Knowledge (nature) 20, Knowledge (the planes) 20, Hide 40, Listen 40, Move Silently 40, Sense Motive 36, Search 40, Spot 40, Swim 24, Survival 24, Tumble 32, Use Magic Device 40
