Foreach is not iterating properly /with wordpress

I am trying to iterate through three recent posts and display their thumbnail, title and permalink.

The first one has a slightly different look so there is an if statement as well to display the first one in a different setting and then iterate throguh the rest. What is happening instead, it is showing the first post three times with styling for both if and else.

I am not sure what am I doing wrong, thanks for any help!

$recent = wp_get_recent_posts( array('numberposts' => 3) );
$i = 0;
global $recent_post;
foreach( $recent as $recent_post ) {
if ($i == 0 ): ?>
<div class="header_recent main">
<a href="<?php the_permalink($recent_post); ?>">
<img src="<?php echo get_the_post_thumbnail($recent_post->ID); ?>"/>
<div class="overlay">
<h1><?php the_title_attribute($recent_post); ?></h1>
<?php else: ?>
<div class="header_recent side">
<a href="<?php the_permalink($recent_post); ?>" title="<?php the_title_attribute($recent_post); ?>">
<img src="<?php echo get_the_post_thumbnail($recent_post->ID); ?>"/>
<div class="overlay">
<h1><?php the_title_attribute($recent_post); ?></h1>
<?php endif; $i++; }
wp_reset_postdata(); ?>

Also, I would really appreciate help with the warning about get_the_post_thumbnail function:

Notice: Trying to get property of non-object on line 29

The function wp_get_recent_posts() returns ARRAY by default, as you can see in the documentation. In your case you need to pass second parameter $output as OBJECT:

$recent =  wp_get_recent_posts( array( 'numberposts' => 3 ), OBJECT );

Also you shouldn't pass $recent_post as argument of the_title_attribute() function. So instead of:

<h1><?php the_title_attribute($recent_post); ?></h1>

You can write:

<h1><?php echo $recent_post->post_title; ?></h1>

And you don't need to declare $recent_post as global.
