First 3 Cultists nearly done

So, I think I am pretty happy with these fellows, and I am considering calling them done. Other than the base of course. Please take a look and offer any advice or criticism they might warrant. I've not done any painting in a long time and I can pretty much say, these are the first I've done to a mostly completed state in a very long time.

This will be a unit of 20 Chaos Cultists of Nurgle. They are meant to take and hold the closest Objective. All I am going for is tabletop quality, and trying to keep it as simple a scheme as possible since I have 20 of these fellows, and another 30 Cultists to paint as well.

Please be honest, so I can get them done. My biggest request is advice on basing these guys. I guess I need to decide on a theme for basing for the entire army to tie them all together. Thoughts?

Painting Cultists

I took these pictures a while ago. I am just now getting around to posting them here. I'd taken them to send to a friend for advice on color. I've not yet taken pictures with said advice implemented... I just wanted to show where I stand and give an idea of the direction I am going. If I can get my sisters camera again, I'll take pictures of the nearly completed models.

Comments? Any advice would be appreciated
