I'll be using my Hashirama biography instead of Roy. Senju in sig. ^.^

I will lead my clan to victory, regardless of who my opponent is, save your breath..
As you jump up and release the wall of fire towards me, I waste no time in creating a rasengan in one hand and water destruction torrent in the other, before combinging them both and releasing a strong tornado of water which heads towards the fire, taking it out with ease and going towards you as a Weak D-rank which would knock you back, preventing you from performing your third technique. This would be possible since water has a natural strength against Fire, and your fire had already been weakened by my Earth jutsu.
As the water knocks you back, your first jutsu would have taken affect and there'd be no swamp left on the ground (Correct me if I'm wrong, I don't have any knowledge of Fuin.) And since the force of the water isn't that strong, it'd only knock you back a couple of meters, allowing you to remain in mid range.
As I give you time to get up from the hit you've taken, I create 3 Wood clones to aid me in battle. The wood clones would be created at the end of short range in the areas to my left, right and the area in front of me. Upon their creation, all 3 would run towards you, with the two on my left and right running in arc. The wood clones would throw multiple Kunais as they make their journey towards you.
Lets see how you deal with my clones..
