Here is my finished entry - a group of Tyranid Warriors called Blade Runners:
There is all of them: Six Warriors and a Tyranid prime.
Note: All Boneswords are sticked on with blu tack since I am painting the models without weapons - just easier that way - one warrior didn't want cooperate hence no boneswords on that warrior.
left one is jumping over a ruin - all of the model's weight is held on one joint and when trying to get the bonesword to stick it snapped - 30mins delay for the photoshoot
right one is charging - tried to make it look like it is carving itself a passage
The next three include the Prime in the middle with some plants (ends of old type lash whips)
The tongues will act as lash whips. They are the end of lash whips - newer type on the left and the old type on the right. But the old type lash whips had a weird end (used as plants above) so I used the "rope" part and glued a needle end to it from the bottom piece of the lash whip.
Prime's boneswords are the Swarmlord's boneswords placed on Warrior arms.
Lower sockets are magnetized so I can use either Spinefists or Rending Claws - the Rending claws are modified hence they're are on them now.
The rending claws have flesh hooks included. On the old type hands I could fit two between the knuckles, but the newer have only thumb and two fingers instead of three, so I placed the second flesh hook on top of the other flesh hook.
