The archives are full of abandoned or unfinished short story sequences. Generally I burn out after about 30 studio hours on the same project. The effort of character design and scene setting usually takes the full weekend away, then my dyslexia hampers the writing and structure until it ends up as a folder in the archives to be forgotten about.
Something like this needs to be a commissioned/paid project to work, I don't think I can get though the more tedious and exhausting aspects without the knowledge I'd be letting someone down if I left it unfinished. My motivation to not disappoint someone is much greater then my motivation to make and finish short stories under my own steam.
This was one from about a few months ago, the premise was an Elven princess and her bodyguard captured by an evil sorceress, becoming playthings of much amusement. I'd forgotten about this side project completely after a trip to Norway and lack the momentum to take it back up.
