Necrons are very simple models, and to do something impressive with them a good start would be basing the god damn thing! Time and again I see models instantly losing a point due to not being based - why?!
The cloth looks reasonably well painted but you've neglected virtually every other detail - eyes, icons, the bandaging around the staff and the pipes. There also needs to be much stronger contrast on the metal itself.
the staff and the cloth both look excelent, but i'm not to fond of the metal, it just doesn't look clean, hte breast plate torso does but nothing else
anywhay kepe up the good work.
