Sticker-bility Puzzle

The Puzzle:

Sticker-bility
The addition sum below is a puzzle I've been trying to solve. The idea is that each type of sticker stands for a different number, but that this number is the same wherever that sticker occurs.



So far I've got it to the picture shown in the second diagram. Can you finish it off for me?
