The painting begins

After what seems like ages from starting this bad boy I finally got sometime to lay done some colour on him. I'm experimenting in painting in a slightly new way for me. I got some glaze medium to try and I'm trying to paint one area to 99% finished, then I can make minor adjustments once the model is 'complete'.
The skin has only had it's first coat, but the armor is 'finished'.

The rust is done using MIG pigments (The new Flames of War branded pack)
