nice to see another nid player!
good combo, I guess you aim for Hive Fleet Leviathan?
I'm kinda new myself, but I'd say get either a wash called "gryphonne sephia" or for a more purple look the wash I use myself (druchii violet) (very thinned on white or it can ruin the effect)
a wash adds alot more contrast to your models and shade etc.
try it, you wont regret it I watched this vid when I was totally new ^^

also, you could either hightlight the edges of the carapace with purple and some white mix
good luck mate!![]()
