The yellow marines are much less daunting when painted in small batches. I think it only took about two weeks of painting on and off to get through these guys. I've got my system down, so there wasn't a lot of "problem solving" to do along the way, and even the embossed shoulder pads gave me less trouble this time around.

The basing worked out pretty well, and the attachment points are nice and snug.
I only have about five Intercessor marines and a couple characters left from the starter set, so I'll knock them out eventually. For now, I think I'll get back to the Skaven tower that I've been neglecting since January. I also need to paint those vampires...
