Why am I getting an unexpected endwhile?

    <?php
        $loop = new WP_Query(array('post_type' => 'portfolio', 'posts_per_page' => -1)); 
        while ( $loop->have_posts() ) : $loop->the_post();

        $custom = get_post_custom($post->ID);
        $special_notes = $custom["special_notes"][0];
        $website_url = $custom["website_url"][0];
        $view_more = $custom["view_more"][0];
    ?>

    <article class="project">
        <section class="thumbnail">
            <?php the_post_thumbnail(); ?>
            <section class="description">

                        ?>

I get an unexpected endwhile on line 35. Can someone help me out?

Missing } on line 29, is my guess.

Mismatched brace on line 29; you don't close your if's {.
