Quick and dirty smoke effects!

 Not much to say about this one! Just some smoke effects made from randomly bent paperclip wires with plastic/glass beads of various size on them, then smoothed out between each other with milliput+fine magic sculpt mix.

Hopefully once primed & ready it will look kind of reminiscent of effect used here on an official model from GW website (credit goes to them!):

Why would a tyranid creature have them? Spore chimneys? Not quite! (yeah I did already spoil it in previous post, whatever)
