This is by far my favorite piece of yours! This piece gave me goosbumps! I ADORE IT! It truly captures the one of the encounter with Sans. His facial expression shows the Sans and remorse that he harbors for not interviening with the players progress before it was to late. Having Papyrus in he back round also gives the viewer a sense of sadness and regret if they have ever played through this route of the game. This is all in all AMAZING! Keep up the amazing work!
