I am a sucker for robed space marines. Like the idea but the effect would have been 10 times better if the blending was given more attention. Also nit a fan of the gold on the bolter, looks out of place to me.
As the painter, I can only say, I've never done blending in my life *lol*
Also, you want a silver bolter on a guy with silver armor?
The gold is there to contrast and for fluffy reasons.
