I'm curious whether or not this operates as a suitable creative outlet for you. Artistic expression doesn't have to be dependent on situational narrative, despite the fact that most of your art is character driven. If you've got ideas that require more effort and time (and it seems you do in terms of ambition), maybe make the daily a progress report or something of the like. It's still a continuous effort, but without the need for a "novel" piece every single day. That's just tough regardless.
