Yes, try and picture it. This can be used both strongly offensively and defensively. You could use this to block against most water attacks, however, it won't last long if water is indeed used against you. It also blocks nicely against most physical attacks and fire. But please keep in mind that it is weak to water and can break at certain parts if hit with a strong enough physical attack. Nicely done. 
Alright, for this next one.
Charge Doton chakra into your hand and then proceed to slam the ground, sending it towards my clone and softening the ground around him to become a swamp.
Make the swamp deep enough to sink him into it and drown him.
