This sleeper looks great! I kinda wish he'd stand there another frame or two after putting his hat on though.
I've made the work-in-progress sprite 24 frames long with a loopback to frame 16; this is so that there's 8 frames of playing room with things like timing etc before we settle on a final version.
In the ones I sent you, try setting the loop to a later frame (such as 20 - this is done in scheme.nxmi under $SLEEPER) and then copy 4 frames of just "standing up" before the lem begins to lie down. Since the last 8 frames are identical, they can just be overwritten as needed.
EDIT: Incidentally, the poll closed at 6:3 in favour of the Sleeper, so I think we can call it there.
