experimenting with photoshop to add the collage clothing

hand craft- 
slower process
show more skill
tricky procedure to get around small details with pen knife
allows me to use pen detail after adding collage to show tone and shaded areas.
photoshop- 
quicker.
allows me to multiply collage material so i never run out
more accurate then using a pen knife to cut out the shapes
allows me to undo cutting errors
more clean cut
crisper image
allows me to alter saturation etc of collage material

after experimenting with photoshop, i have chosen to stick with hand craft collage because i want to be able to draw on top of the collage to add more depth, which i feel i would not be able to do to a hand crafted standard photoshop. however, i am still going to scan the finished collage/pencil pieces into photoshop to polish off the final pieces, adding backgrounds and text etc.
