Don't get to do sci-fish things often and i had some free time to mess around with personal work and workflows.
Process :
Kitbash3d Outpost pack as a base, changed up the materials a bit and added details using meshes from Ian Hubert.
Plants are a mix of Scatter5, Botaniq blender addons and MaxTree.

Finished it off with 2 or so hours of paintover and post processing in photoshop.
The whole thing took around 6-8 hours.
