To be upfront, I did not design this, they are based on concept art by HanHog https://www.artstation.com/hanhaoyuan
I saw these the other day, and really, really like the aesthetic and style (No idea what they are), so decided to have a go at modelling it, as there's no way I could design anything so cool! I limited myself to only blender for models, decals and materials, trying to get better at material design. Really happy with the result, even used the Compositor in Blender, which I haven't quite got the hang of yet.
Anyway, enjoy, and big up the original artist, really awesome stuff.
