This will require a few changes to the code, not a simple 1 change fix. I also personally think the express theme is not quite ready. A few things don't work well there. I personally think you should use another theme.
It's a fairly new theme, as one review stated "The theme is really neat and beautiful, but it has a lot of bugs". Personally, I think Debut would be the best free theme to work with. It's easily alterable and can be made to your liking.
Nonetheless, your desire for the collection to be made to look like your picture, it will require multiple edits, further you would need a hire a developer to make such changes.
