I'm trying but I am by no means a great artist of ship design I mean If I do succeed in making some myself il post them up but basically idk if any of you have played sins of the solar empire... beautiful rts game btw...

The ships in that game have a great design and my favourite ones with the best back story IMO and types of ships easily is The Advent.

If itl let me i will link you to a few pictures of the designs.

This is the Titan or Flagship of the Advent with the ability to fire a big charged up laser beam focussing their telekinetic hatred onto their enemies https://pre00.deviantart.net/d9d2/th/pre/f/2012/294/5/b/soase__eidolo_advent_titan_by_ignusdei-d5iizwg.jpg

I would love it if I managed to make something that awesome but I really doubt I will be able to.
The one I am going to try and make is this one The Progenitor Mothership of the Advent

Wish me luck I've seen some insanely inspirational ships on this workshop hope I can come close to that quality.
