Scene one animation complete

This week we have finished animating the first scene of the film. I have finished animating the Grim Reaper as he makes his way through the graveyard. doing so has reveiled a few little problems as well aas one problem which has buged me whilst animating. grim's sleves are a bit of a mess. it isalmost imposible to move or rotate the arms without the sleve deforming very badly. to make it worse thecontrols i carefully planed do nothing to help the way they deform.
i dont know wether to fix this problem before continuing or to just work with it as it is.
i feel frustrated when problems like this are out of my control as idealy the sleeves would not be modeled in this way with them already hanging dow from his wrists as it make it extreemly hard to make the model look good in any other position than the default position.
i feel that it is very important to understand the who prossess when contributing to a production. for instance the model which is intended for rigging shold not be done just to look good in the on position but had thought behind what is intended for it animation wise. i feel frustrated by this many times with James models, for example grims sleeves, its all fine making them droop nicely when the has his arms streached out to the side of him but it make it imposible for me to create a rig which can then make the sleeves look convincing once his arms are at rest by his side. its amazing how small things become big problems further down the line.
