6 months post-op- Difficulties lifting up my brow, could it be nerve damage? (Photos)

I had a temporal browlift 6 month ago. There was a lot of bleeding during the procedure especially on the right brow. Now 6 month later, I can see that my outer brow on the right side isn’t lifting like the rest of the brow. So the middle of the brow is lifting fine, but the outer brow looks odd which gives me a sad appearance. Can it be nerve damage or what is it?
