Wood:
Mokutn hijutsu:Jukai Koutan
--This is a good one, but i think it could be improved on. For instance, rather than a mass-aoe, this could be an attack Sends roots in a diagonal/horizontal directions and harms whatever it touches. That way, it's alot more fair.
Moku bunshin
Wood capture -- Works great, but one detail, IT SHOULDN'T WORK ON WATER!
mokuton:mokujou heki--Take this one out, the "Huge Barrier" would provide more defense, though i have another good idea for this one...Revise it to be a wood-element version of Doton: Doryuuheki (Offensive Jutsu)
and mokuton:shichuurou no jutsu--Protects the user only on the front and sides, still allowing mobility through the ability to turn and attack rear-attackers
