O_OokayNo, it is not, I am going down the list. And actually, this jutsu is very flashy, and would serve better as a defensive wall or to control the effects around the battlefield.
Next one...(Katon: Hokori Tenka no Jutsu) - Fire Release: Dust Ignition Technique
Rank: A
Type: Offensive
Range: Short - Mid
Chakra cost: 30
Damage points: 60
Description: The user will first ignites a flame of fire across the ground infront of them and then they will enhance that fire with a gust of wind to extend the range of the fire
Please proceed to create a fireball in the same way you've done before. However, focus your chakra into the middle of this fireball to give it an explosive nature.
Then, proceed to send it directly at my clone, exploding on impact. Describe the impact it has on the surrounding battlefield.
*I mold my fire chakra, then channel fire chakra into my chest, as I do that, I apply pressure and spit it out as a ball of fire, I make sure to focus more of my chakra into the middle of the fire ball in other to give it an explosive nature, then I send it towards your clone, the fireball explodes on impact with your clone*
The surrounding will undoubtedly not remain the same, the explosive effect will destroy anything within its range<_<
