Here's some helping tips:
Create each parts separately before glueing them together. By that I mean;
Make the hands, then bracers and then arms.
Make the legs, cuffs and feet. Glue the sole at last.
Make the body.
Make the head.
Make the skirt (don't close it completly)
When you've built every parts, start putting them together.
Glue the arms to the body.
Glue the head to the body.
Glue the legs to the body.
Glue the skirt around the body.
you can also glue the legs inside the skirt and glue the skirt to the body.
If there's a cape, glue it to the back of the body or leave an opening in the back and glue the cape directly in the body instead of the back parts.
It's a pretty useful trick that you can also use for moonkin's fur.
For the shoulders (the equipment piece, not the body part), you don't see inside them so you dont have to make them perfect.
So don't worry about leaving an opening, you're gonna glue that part to the arms anyway. It's easier to close the shoulder from the inside if you leave it open.
