Added a real life image to an illustration. How do i make it match?/Look better?

Question

I've added the lei to the dog and it just seems wrong because the dog is cartoony and the lei is realistic, it contrasts too much. how do i fix this?

Answer 1

You could:

• draw it
• trace it in a vector programme such as Inkscape or Illustrator
• apply Photoshop artistic filters to "sketchify" it

Answer 2

I selected the lei, went to

Filter > Filter Gallery > Cutout

And played around with the values until I got something that looks half-way decent (I ended up with 5 levels, 3 edge simplicity, 2 edge fidelity).
