Here are the finished scorpions. I really need to work on my camera taking skills, they are still not quite there yet. These guys turned out great. I found that adding yellow to the green and browns, made a much better highlight color.
I love using these guys on a flank move. They have some great strength 4 (great for eldar) and a great 3+ save which means they won't fold like wet toilet paper under pressure. My favorite memory of these guys in battle was once when they took on a squad of ork bikers, and it came down to the exarch vs the nob with a powerfist. After the last die had stopped rolling, both were dead with the other's powerclaw around what was left of their neck.
