OK, I can see the movie in QT.
I'm not sure what you are trying to do in the screen, it looks like you have a constraint selected but are moving things around?
This was made to address one particular challenge in posing Shaggy in "the Door is Stuck" exercise... putting his feet on the door, leaning him back and yet getting his arms to reach the doorknob. However since there is no complete "Door is Stuck" video yet, it may also give others useful exposure to general Shaggy posing workflow and AM2001 Rig circumstances.

the resulting PRJ: The_Door__s_Stuck_ShaggyAtDoor.prj
Note that I've posed Shaggy in this pose at frame 0:00. If you were really doing The Door is Stuck, this is not the pose you would start with.
That's a toon render of an actual shaggy so it must be possible.
You don't have to do that exact action, you can do anything where he's got trouble with the stuck door.
15 steps is a lot of steps! I bet it would be hard to find a movie where a character takes 15 steps in one shot.
Maybe something about your shot needs to be rethought?
Part of the problem is that "The door is stuck" is a bit too big a leap from the previous animation exercises in TAoA:M.
Another part is that the strategy of Blocking->Breakdowns->Polishing is not introduced. That would help you approach the task of dong a "scene" in efficient manner.
That's a huge concept and probably a bigger one than could be handled in the short tutorials format of the original TAoA:M but I hope to address that in the NewTAoA:M.
For now, show us what you have so far and maybe you'll get suggestions. Make sure it's compressed so we can DL it quickly.
Rusty... is that an actual person you've modeled?
If so, you might take a pic of him with good light and start comparing that and your render and say "what's different between the two and how can I eliminate that?"
If there are groups of bones you like to isolate, as Nancy mentioned, and return to them often, the PWS has Enhanced Selection Filters that make them easy to recall.
You could call them in the PWS select them there, and then Tack them in the Timeline to work on them there.
That's the big distinction. You have to select something before it will show in the "Timeline". You can turn on the Tack icon in the upper left corner of the Timeline to make things persist in the Timeline even after you select something else.
On the fine wrinkle lines... In his "Digital Lighting and Rendering" book Jeremy Birne suggests to add some red at the bottom of the wrinkles. Same color all the way through is unnatural.
If you want an extra texturing detail to add... water/rust stains dripping down from the corners of ledges and where metal has been bolted to brick walls.
It's beginning to come back to me...
Perhaps the problem is the automatic "ambience intensity" setting of 30% that imported Props seem to get for no great reason.
When i drop an imported prop into a chor it's properties get a "Surface" subsection that has this setting exposed and you may reset it to 0.
Alternatively, if your prop has decals, they may have a similar property that needs to be reset.
Example below . The right vase is an imported OBJ where i've reset it's Ambiance Intensity to 0 so it now resembles the original spline vase.
