SCI FI - update WIP - Astrotug - based on John Frye concept art

Original concept art made by John Frye, look at more his amazing work here: https://www.artstation.com/artwork/J9k4B0. Another attempt after a long brake. Some details added before it go to the texturing. I can't wait to see it finished :) So, I decided to add another object together with Astro Tug. Gate switch from great concept made by super talented artist Carlo Balassu.
