Necron Monolith

Hi Guys, heres one for any Warhammer 40K fans or general sci fi fans. i am working on a Necron Monolith, i thought it would be a fairly easy project due to its general blockiness, but i’m getting a bit carried away with attention to detail so its taking me a while. So far heres a weeks worth of effort. I havn’t been using Blender that long so im taking this project quite slowly in an effort to learn as much as I can. Eventually i want to give the model a gritty realistic look rather than looking like a model. Love to hear your thoughts and feed back so far. For those that dont know what a Necron Monolith is i’l post a reference picture up too.
