It isn't just the actual measurement of each, it is their visual weight. Visually the cowboy and the sign feel the same weight to me. Enlarging the font of the title and changing it's background color may change the visual weight. Also making the cowboy a bit smaller would help in multiple ways: it would move him away from the edge, give the author and illustrator text more room, and create size variance but still keep him in front of the sign.
I get what you are saying now--I'll play around with it!
