Nice designs. Its a bit late for me, so ill be checking this out tomorrow. Some things I noticed to get this rolling.
1) modest hue shift. more like no hue shift actually
2) modest use of grey metallics. usually used as small decoration and to show weaponry
3) high contrast stripe patterns. in 90 or 45 degree angles only(except for angled edges)
4) details galore. I leave this for the next person, maybe we can spot some standard design elements?
5) outlines forbidden
6) eyeball/jewel target areas
7) theres a range of values used that i haven't quite figured out, but i think it key to the style. The red ship at the very bottom has a narrower range of values and I think this is why it sticks out. Almsot all have a full value white as a highlight or stripe which i think is important to the style. I'm not sure if there's a 000 black, but if there is it's used sparingly.
I also notice that there dont appear to be many 90 degree corners. Also important I think to note how highlights are used on the points where the ship angles.
MAybe someone could put together some palettes for a couple of these ships so we can look at the contrast of each shade
These designs are hot. Good night.
