Concrete release is cool. But my favorite is thunder release. Some more: Maze release? (description: made of earth and wind, the user can create a maze at will. The maze itself in somewhat like a genjutsu, the victim will feel like their in a maze. The user will now be able to strike as much as desired. weakness: The weakness is the jutsu must be continuously held.)

Mirror release? (description: made of water and earth, {Warning this is very similar to my last idea} it creates a mirror like genjutsu {or real mirrors if you like} and has the victim caught in their own reflection. The mirrors can't be broken but must be held by chakra to keep them impenetrable. The user can now strike but this jutsu can't be held while using another jutsu so the attack must be powerful.)

These are off the top of my head so they probably suck. If you want we can even combine them.

As for poison release and/or clay release,

Poison release: The user can create and wield poison in any form, liquid or gas. Possibly strong wielders can put poison into someone's bloodstream.

Clay Release: The user can shape explosion clay into any shape and either harden it to make a hard shell or Armour similar to Gaara's, make it explode or liquefy it to create sticky slimy goo.
