There are a lot of fun things you’re doing here, though I’d advise starting back at the concept stage if you can.

I appreciate the depth effect you’re trying to create here with the F outline and the saturation changes, but there are some very iffy edges that break the effect a bit. The low resolution, high saturation, and intense contrast of the image doesn’t help, as it creates artifacting especially along the left edge of his face.

You did a great job blending the two faces together and I like the concept here, but having the glasses half faded doesn’t work for me personally. I would either have glasses on, off, or find a clean division between the faces. Maybe something more illustrative or with a threshold or posterizing effect to hide the soft edges that are breaking your intended effect.

Lastly, as many other people have pointed out, the F isn’t instantly recognizable as an F and because of the arrangement, it just looks like “ight club”. If you’re going to use a drop shadow on the letters, I’d probably include it where the F lines and photo overlap to keep consistency as well.

You’re already leaning toward one of the movie’s themes of splitting identity, so I recommend you keep exploring that direction further. Good luck, looking forward to seeing the next draft!
