Good job. Oh, and I forgot to mention. If you think of any good combos, list them in your analysis, you can look back on this later and get ideas for fights that way!
Im going to start listing two techniques at once, but if I see that you aren't putting as much effort into each technique, we will go back down to one. I think you can handle it though.
(Doton: Nentsuchi Otoshi) – Earth Release: Sticky Earth Drop
Rank: B
Type: Offensive
Range: Short – Mid
Chakra cost: 20
Damage points: 40
Description: The user does 2 handseals (Ram → Snake) and creates an opening within the sky, which drips down onto the opponent a large amount of sticky mud (in all similar to that of Swamp of the Underworld Technique), covering them. The mud is very heavy and thick as well as adhesive, making it impossible to move if caught and easily crushing an enemy underneath. It’s normally followed up by Lightning release: sixteen pillar bind to create a giant oven around the opponent and then using Fire release: Firing biscuit technique to ignite the oven, hardening the mud and immobilizing the enemy target
Alright, so this one is pretty straight forward. Two hand seals to open a portal above your opponent, releasing a very sticky, very thick, mud like substance. If you are successful at covering your opponent, it will restrict their movements for a follow up attack.
(Doton: Otoshibuta) – Earth Release: Dropping Lid
Rank: B
Type: Offensive
Range: Short-Long
Chakra cost: 20
Damage points: 40
Description: After doing the Snake handseal and slamming his hands on the ground, he user creates a portal above the target, high in the sky from which a giant, boar-shaped, earthen lid drops and falls on the target, trapping it underneath. The lid can be hollow or solid, depending on if the user wants to deal damage to the enemy or not. Because of its size, to safely used, the lid has to be created at least mid range from the user otherwise he will also be caught inside. The biggest lid can dwarf a boss summon like Nagato's Dog or Gamabunta.
Fairly straight forward technique. One hand seal followed by slamming your palms on the ground to open another portal above your opponent. This time though, you are releasing an earthen structure that has a lid shape. Multiple uses, customizable in relation to density and size, decent technique overall.
