Can i use my own html?

Hello, help me please.
I love your plugin and he works fine, but i want use my own code for displaying CRP, like this:

<figure>
    <a href="<?php the_permalink(); ?>">
<?php
if ( has_post_thumbnail()) { the_post_thumbnail( 'thumbnail'); }
?>
        <h3><?php the_title();?></h3>
    </a>
</figure>

Is there some way to do this?
