How to make a peeled sticker effect [Photoshop]
this is wat we are going to make:

step 1:
make a new document. I used 300×300 pixels. (depending on how big you are going to make)
Step 2:
select round marquee tool and make a circle. after making a circl, fill it with whatever color you want.

Step 3:
Select polygon lazzo tool. this is located under the marquee tool. Once the tool is selected. make a selection like this:

Step 4:
press ctrl+C to copy it. then delete the selected area.

Step 5:
make a new layer above the circle and name it as peeledpart. then press ctrl+V to paste the one you copied at step 4.

Step 6:
press ctrl and select the the layer of peeledpart. once it is selected, go to edit>fill and fill it with whatever color u want. i used white.

Step 7:
after filling it with whatever color you want, press ctrl+T and rotate it oppositely to have the same effect with the pic in step 6.
Step 8: [Applying more details on the sticker]
press ctrl and select the peeledpart layer again. then select the gradient tool. appply gradient on the selected part.
Step 9:
use brush to make dust. in this step, you can do whatever you like as long as it will be like dust or can be cutted. it depends on what you like. just play around it.
