I think the shadow on his temple changes too much and is distracting. Eyebrow movement like that affects the position of the skin on the temples, but not its shape. What it does affect visibly though, is my forehead - I get forehead wrinkles when my brows are up.
The single-pixel shadow bits at the bridge of his nose look a little strange, and give the bridge a symmetrical look that doesn't feel right for this angle. Also, the narrowest part of the bridge should probably extend vertically a bit when the eyebrows are up, since they pull that skin up.
Lastly, I think a more "golden" (redder) yellow would work better for the text.
Here's an edit. The timing might be off.
I tried to implement everything I mentioned above, but I didn't include the forehead wrinkles because they were too distracting.
