Arctic Tele- and Techno-Vipers

Finally finished Arctic Tele-Viper and Techno-Viper (heads obtained from Brian Kauffman at con this year). I wanted to make these guys look completely different, rather than just add their heads to Snow Serpent bodies. I tried to use mostly production parts that were not from cold-weather specialists, yet that still look the part after painting, to further distance them from production figures. Can you identify all the parts used? Post your answers below!
(I'll edit this post eventually with the full parts list)

Apple Barrel white
Craft Smart medium brown
Craft Smart black
Testors light ghost grey
Testors gold
Testors silver

Great customs.

Wow! Great modding on their heads, mate! I love the color choices too.

The head modding was all done by Nova. All I did was paint.
