Okay<_<Very good, but you forgot to look at the size of the dragon.
Since you are able to control it, it can go anywhere on the battlefield and can also potentially block your enemy's vision. As said, it can also be used as a defense mechanism against Wind attacks, as the dragon can basically "eat up" the wind and grow stronger.
Now, much like the concept earlier, take this scroll once more and manipulate your fire chakra so that a tiger is released from it, running towards my clone and attaching on it. (<- Purpose of this.)(Katon: Bakuryūgeki) - Fire Release: Exploding Dragon Strike
Rank: S
Type: Offensive
Range: Short - Mid
Chakra cost: 40
Damage points: 80
Description: The user through use of one their scrolls will summon a large flame dragon that is directed towards the enemy target and explodes upon impact.
Then, proceed to cause it to explode, causing massive damage as it does so. Describe the impact it has on the clone and the battlefield.
*I take the scroll, then I open it, and start channel my fire chakra into it, I continue adding more chakra into the scroll till its enough to create the tiger, then I manipulate my fire chakra, releasing a tiger made of fire that is directed towards senseis clone, it runs towards the clone, and attaching itself onto the clone, making it difficult for the clone to evade the damage that happens, as I cause the tiger to explode causing serious damage and the clone eventually disperse*
well in this case, the clone is burnt pretty badly, for a normal person what will remain is ashes>_> further more the clone was at the center of the explosion, which makes things worse, explosion usually causes a large sound, it has a considerable amount of force, pushing away anything/person around the explosion as well as burning them, and destroys the surrounding within its reach
