Quick opinion/advice.

should I highlight all the claws with a typical black>gray>white highlight that I usualy do for tyranids, or should I do something more in line with the "spooky" idea of this model, as in black>orange>yellow ?

Man I forgot how much fun painting tyranids is. This guy's coming along pretty nicely and decently fast too. I might even finish him tomorrow but I have a fair bit of highlighting and vfx stuff to do.
