This is really nice! Iv released a free theme in a similar vein for anyone looking for an alternative in the same genre :)

Demo https://demo.sitecreate.io/kuva/
Download https://www.sitecreate.io/themes-and-templates/kuva-free-wordpress-photography-portfolio-theme/

Have submitted to WP.org of course so with some luck should be widely available in a month or so :)
