So far so good mate, and good to see you painting again after the trouble with your peepers earlier on in the year!
The OSL looks cool, I personally would have taken the plasma light source a touch brighter but thats just personal preference. As it is now however, it does look nice and subtle, which is what you were after!
The only bit that would give me cause for concern ATM is the armoured shoulder highlighting. The blends from the darker brown to the more orangey brown are well done (although I can\'t help feeling a highlight and hot spot would sit there IRL). My main worry is the khaki/bone edging. It looks too stark, especially as the other colour is blended well. I also think its too thick and would work better as an extreme highlight.
Keep up the good work Dan, and hope my rant has been helpful, as intended.
