Header Logo in the middle

Hi, thank you for the theme, is awesome!

I used this code to remove the gravatar and add my own logo

remove_action( 'highwind_header', 'highwind_site_title', 20 );
add_action( 'highwind_header', 'my_custom_logo' );
function my_custom_logo() {
?>
<img src="path/to/image.png" alt="" />
<?php
}

It works great, but the logo align on the left and i want it in the middle of the header. Can you help me, please?

thank you!
