It was well enough, but you skipped a few intermediate steps I would have like explained, such as actually turning the chakra into mud using shape manipulation while it was in your throat. Please try to take note of that in the future.
Now, I don't believe you know the Assimilate All Creation technique, which is a Ninjutsu technique, so I'm afraid there are a few Doton techniques we must skip over. Whenever you learn that Ninjutsu, be sure to inform your Sensei you need training in the corresponding Doton techniques.
So, for us, that means next is:
(Doton: Doryūha) - Earth Release: Earth Flow Wave
Rank: B
Type: Offensive
Range: Mid - Long
Chakra cost: 20
Damage points: 40
Description: After performing the required hand seal sequence Rat → Snake → Tiger the user creates and rides a wave of earth that can branch of to attack from a distance. The user can also use the technique to manipulate the terrain and trap the target by wrapping earth round their legs preventing them from moving.
The handseals are listed.
A useful multipurpose technique, it works by simply infusing a large section of earth with your chakra, and basically manipulating it how you see fit. Give it a shot: make a small wave to ride upon.
