Progress so far 3 Tactical Squads, 10 Poxwalkers and 2 characters.
Modifications here were swapping of Powerfist and Backpacks between each model. Removal of various extra bits like the bells and flaming things (whatever they are), and added Bolter for the former unit Champion. The sword that the running dude had was given to another model.
Guy with the tongue sticking out (my favourite of the new models so far) got the sword from the running guy in the 1st picture and the arm off of the grenade dude. Rest of the changes were simple arm swaps, and inclusion of the skull on the stick to cover up a gap in the model on the far right.
Basic head swap for the guy on the left and addition of a Deathwatch heavy weapon and an old CSM head for the guy on the right. Added a handle above the right hand for the heavy weapon guy after the picture was taken. All the models will require some green stuff to fix a few holes here and there and I might have a go at adding extra tentacles as well.
