Wrath
*Yahiko begins to absorb natural energy, condensing it into his right fist to the utmost limit of his capability. When he feels he is ready, he moves to punch a large, dense boulder, releasing the condensed natural energy at the very moment of impact, sending shock waves of through the boulder. The end result is the natural chakra causing the boulder to shatter apart into dust.*
So... That was Wrath I take it?
Pride
*Yahiko then creates a clone that moves to throw several giant shuriken towards his real self. Before the shuriken hit, Yahiko pulses natural chakra to form an aura around himself. As the giant shuriken are about to hit him, Yahiko channels slightly more chakra to the point of impact to 'harden' the chakra (metaphor) causing the shuriken to harmlessly deflect away from him with the flick of his hand.
Then, rushing towards the clone, Yahiko sharpens the natural chakra aura around his right hand, using it to enhance his next attack with razor sharp natural chakra. One swift, horizontal slash with his right arm, sees the clones head part from the body momentarily before the entity disperses in a cloud of smoke.*
I... I feel compelled to make a Super-Saiyan reference here.
Sloth
*Deactivating the aura, Yahiko then releases natural chakra into the area between him and a tree, causing the area to be dense with the natural chakra. He then throws a giant shurkien towards the tree, watching as it hits the area filled with the viscous natural chakra, causing the shuriken to loose momentum and fall to the ground before it even reaches the tree; a distance it would otherwise have made without issue.*
Greed
*Yahiko then absorbs some more natural chakra, focusing it into his muscular-skeletal system to reinforce and strengthen it. This allows him to lift great masses that he would not normally be able to withstand without injury, while also allowing him to run at increased speeds.*
Envy
*Yahiko creates another clone, sending it a short distance away from himself. The clone then sends a powerful ball of water towards his real self. Focusing on his control of natural energy, Yahiko uses it to form a sort of U-bend in mid-air to catch and redirect the attack back towards his clone.*
Lust
*Yahiko then channels natural chakra through his body, transforming him slightly to give off an aura of physical perfection that makes any onlooker compelled to not harm, while being unable to take their eyes off of himself. The technique is so powerful that it takes over the base instincts of whomever looking directly at him, meaning it is not something they can actually resist or release themselves from.*
Gluttony
*Absorbing a large amount of natural chakra, Yahiko then creates a Raikiri on his left arm before adding the natural chakra gathered into it. The Raikiri starts to chirp louder and grow noticeably larger than before, with the erratic bolts of lightning flying off it looking just that extra bit more fearsome.*
