Puggy Brewster - Edit

Made a few small edits, but still having a hard time with this.
Would love some feedback! What do you guys think?

On all of them, I changed the slats in the glasses to lines.
The top left one has darker lines on the glasses. To the right of that, they are white. Bottom left is sans forehead wrinkles. Bottom right has reflection lines in the glasses.

I'm leaning towards the bottom right with the dark lines on the glasses and reflection.
