I've been meaning to draw Asriel for some time - and with Homestuck back from hiatus, I was musing the connection of Undertale and Homestuck. I had a sort of lightbulb moment of Asriel as the time aspect - Prince also happens to be a Homestuck class. (Granted, Homestuck godtier outfit designs are apparently determined by said class, I don't really like the design of the prince outfit and went with something closer to Asriel's outfit.)
