For the most part this is good, since I don't have a generalized explanation of Earth Release, I'll just point out a few things. Firs thing is Earth release doesn't just deal with manipulating your chakra into pre-existing earth, like suiton, you can create earth and earth based techniques with your own chakra. In the Narutoverse, the way one manipulates the elements is based on the types of chakra. Doton chakra is a type of chakra, one doesn't use ordinary chakra to manipulate the elements, they use the type of chakra of the element they want to manipulate, and that'll be the first thing we get into when the training starts.
We'll talk more about the elemental combinations later, however, Earth+Wind+Fire is what creates Dust Release, not Earth and Wind alone. You can create dust through the useage of both elements but it's an entirely different entity than Dust Release as used by the Second and Third Tsuchikage.
Any Questions before we proceed?
