I like the model and paintjob alot. The only sugestion i have to make it more Nurglelike would be to replace the axehead with a scythe since the axe is commonly associated with Khorne and his kin.
Grand Funk Rail Gun, portlandspacemarine, Thanks a lot!
Dark tones already impose nesmog, because I do not miniature. Sorry for bad English. Well, maybe fun is obtained, as I was asked, and I work.
Plotrekhood, you don't have to be an asshole, your space maine is not any better. I in fact think this is a pretty interesting take on the figure.. there are no rules for how to paint your own miniatures and I think a Khorne army in these colors would look pretty darn cool on a tabletop.
Hanataro, the rust effect looks really good, I think the skin would look perfect if you added some darker tones between his fingers for example.
Keep on painting, Forge world is a heck of a lot of fun isn't it? :)
