I think that the hatter is definitely a better choice. But since it's so small, maybe you could crop it down to just a "head and shoulders" framing so that it's a little tighter and easier to see? Again - just a thought. It also fine works as is. With that hat, he does look a little like a magician.
If it's easy to change, maybe you could "revolve" it. Put in a pic of one of your new characters from the apple story. Or swap the pic out with different characters every month or two?
And thanks for the font color change. MUCH better.
