Deathguard Lord Part three

As previously mentioned, I make haste glacially slowly.
Following on from Deathguard lord 2, here is the latest update on this long running saga.
Most of the colours are now blocked in.

I have a number of icky wounds, veins and pustules still to detail and I need to do a lot of finishing.

I am still not quite sure how to indicate the unnatural decay of the axe, 'normal' rust techniques just do not feel rght.
