Thought about how I wanted to do a Gaster drawing. But then decided: no, I haven't drawn Sans much lately, and I feel like I'm forgetting how to draw him. 

So was like, why don't I draw classic Sans? 

And Flowerfell Sans...

And Inktale Sans...

And Errortale Sans...

So somehow one Sans turned into 4. xD

Probably could have turned into 5 now that I think about it, because I could have also done Mafiatale Sans, but... 4 is a nice round number I suppose! (Plus didn't really think about it at the time-- Sorry Mafia Sans! Can tell he's already glaring at me...)

And in case you wanna know, this drawing took me roughly 8 - 11 hours. xD Probably the longest I've ever spent on a drawing? I'm not even sure. I just know I haven't worked this hard on a drawing in awhile.
