Ok, so I realized I never uploaded this one to dA.
This is a very old space signature tutorial I made specifically for the mAsDesigns community, but seeing as I closed that a while back I'll submit it here too.
This one became the most popular tutorial to ever hit proboards, peaking at 135k+ views.
I hope someone learns something from it, and I hope to also see it become popular here too.
