Really need to download that app at some point then I think just mixing in more shades of brown and incorporating some 'knots' in the wood on larger pieces could be somewhere to look, though for wooden designs I'll grant that Helterskelter's Steampunk Skitarii have always been a inspiration for those sorta things.
I'm getting along using one of the stealth drones as a tester for what I want to go for whole model wise. Really happy with how the white and weathering has come out, though now I've reached an impasse on the 'stealth' section. While I do like how the digicamo looks, a friend has pointed out how tau adaptive camo would feel like it should be more 'advanced' than just that. Additionally, the pic I took before adding camo (jet black) does look pretty darn good. As it stands I'd ask for votes, should I
1) go digicamo on all of the stealth side
2) go jet black on the stealth side (with grey highlights admittedly)
3) have an amount of digicamo, then following the same route parallel as the previous have another 'energy' line, then jet black after that? Like the digicamo was the buffering before going full stealth
Added a pic of the vague base style for reference
Any comments/suggestions are appreciated!
