Here are some sigs I managed to make from various pieces of art from the main game site.
Empire
Federation
Jericho
Btw to set up a sig you wish properly download the file(s) attached to this post. Unzip it and in it you will find sigs split into two even pieces (sig1 and sig2) which you need to upload to your signature box in appropriate order. Enjoy! Say thanks if you like them!
