I suppose its a matter of opinion when it come to shaping and how realistic you want the finished result. I prefer to shape myself but i will let you decide for yourself!
Taking a picture you have cut out and layer over your base print using silicone glue or sticky pads.
which will then look like this
Now for shaping!
you will need a foam mat,a hockey stick shaping tool and embossing tools varying sizes
Taking your cut out pieces I ve started with part of fur stole.
Then turn over so right side up use embossing tool to draw the creases in the fur. Don,t worry that its gone flat again as you can carefully curl round again.
Next is the hair keeping it right way up draw with hockey tool over hair band so that there is a ridge between fringe and hair.
then turn over now staying beyond the ridge lines shape the fringe then the hair
it should then look as below.
now work on the woman s face. starting with the eyes carefully draw over them with embossing tool ,eyebrows,nose and lips.then wrap face around(right side up) the middle of your embossing tool
now line up separate pieces and stick in place with silicone glue or foam sticky pad. Ive added feathers for effect
