I've been playing Necrons with my same old painted models for years but unfortunately I still don't have any pictures.
To describe them just a bit though, my 'cron army has a very strong egyptian motif with colors like golden yellow regal blue and hawk torquoise forming the primary colors in my pallette.
For metals I opt for gold wich is pretty much only used on the guns and the army is filled with lots of ancient looking conversions like an egyptian headdress on my lord(Veteran Necron players will know where I got that idea from).
Also the flesh on my flayed ones has been painted to look old and dry as opposed to fresh and bloody to make them look both different from the average flayed one and to mimic some mummy-like overtones to fit with the rest of the army.
P.S. Kore, thats a very unconventional approach to the Necrons, but well done nonetheless. Very fresh indeed.
And Pickle, Great looking army! Brilliant way to break out of the 'metalics cliche'. DullSpike, if you follow examples like theese guys, you can't go far wrong.
