I like this. I will draw a character in two different poses every day. Until I introduce some of the main characters in my comic, I'm just going to do different Sans variants so I can get their looks down. I am going to use colors because some characters might get mixed up without colors. If this is a problem, please direct me towards a more appropriate thread.
Here's Nightmare (Shattered and Passive):

Oh my gosh, I had so much fun drawing my little dark angel prince. Isn't he so cute and pretty? I loved doing the spectral wings. Any advice on doing a tiny galaxy pattern for the apple soul? I use Microsoft Paint. I did my best at any rate. Oh, and this is Passive Nightmare after the shattering. Just want to clarify. Feedback please
