you did a fine job , pleating the tail is a waste of time .do not pull the tail down tight and tack it out taunt , that thins out the fur on the lower back which is why some went to pleating them to bunch up the lower back fur. just tack it out as it lays when pull down on the board . you could have pinned the front leg holes shut or just left them a hair longer so there was a stub sticking out away . mouth is a little open but should be fine as is.
I sell many put up just about like you just did and get top dollar for them so don't sweat it.
