It has been slow going on these old skool Tyranid Warriors, I've been working on them sporadically in-between Dreadfleet ships. I've painted a lot of Tyranids in the past (including these back in the early 90's) but I must say, the detail on these models is incredible. You can see the organs behind the chest carapace, there are reptilian scales with veins. They're just a joy to take your time over picking out all that detail. Hopefully the picture shows the depth to the red with the dark shading and the subtle orange highlights.
