i like the texture of those wires too, i used them extensively on my nurglefleet.
but they could look a little bit to mechanical. but give it a try and just paint them. and if they don`t look right, it`s easier to cover them with gs, than removing gs from them.
can`t say much about your fleet list, never play`d them. and only play`d one time against them.
but it doesn`t look overpowered, what i like!
