I hope this is useful in someway... I made this tutorial as I saw some key chains on Amazon and decided to challenge myself to make one... this took me approximately an hour to build, so with instructions it might take you less... Go SNK!
make a cut in the tin can... be very careful to cut yourself
this is the shape you should end up from step 1
carve out the wings with a knife or with any available sharp object within range
Punch the hole.... this can can be done by stabbing the metal with a small tip screwdriver or with a compass/divider from a geometric set. be careful not to get injured in the process
Color in the wings with a blue Sharpie and whiteout (white nail polish can also be used)
Step 6: Fin!
Hoozah! the keychain is in your hand :D ... celebrate or add a chain to transform it into a necklace.
