I had some trouble deciding on how to paint the taser goads. I tried to mimic the GW paint scheme but with a green instead of the blue. I also painted the bulbs on the backpack to match the taser.
I was unsure of the wires as well, I ended up with a red wire I also caught the wire on the backpack and painted it red to match.
I really like the GW technical paint and how it turned out. I added a layer of modge podge to seal it in since I have seen some of it flaking off on other models.
It is hard for me to know when it is to much highlight or not enough highlight. I think I did a decent job on these guys. The purple is a little out of place. I probably need a tone in between the 2 I had for the highlight.
The "rocks" are bits of cork painted up grey. My wife helped me one night while I was cooking up supper. Thanks Dear!
Next up in my Skitarii army will be another Dunecrawler. I am looking forward to painting another large model. I am also looking into another way to magnetize the weapons.
