Sigma Posting (Follow on BS)さんのイラストまとめ

Technically, the "prototype" listed here for the Biggy Man edit came second, as I kept adding to the design over and over.

I felt it was getting too busy, so I went with a "less is more" mentality and reverted it to a previous design.

Xi Tiger's edit was going to have a much bigger head, but the original was both too big and too mechanical looking for the meaty Xi Tiger body.

X6's Slime Sigmas definitely fit the look better. Usually I go for the goofier Sigma sprites for these, but I made an exception.
