I get what you’re trying to do, and I’ll post the code below with how to do it using a flat array but it’s unclear what the_query is or how it relates to Advanced Custom Fields. Until the actual code you’re using is posted the below may be a good starting point for you:

<?php
$image_array = query(); // Whatever you're using to query the images

// Ensure have an image array to work with
if( ! empty( $image_array ) ) { 
	
	$per_block   = 4;
	$total_items = count( $image_array );
	
	foreach( $image_array as $index => $image_id ) {
		
		$nice_index = $index + 1;		// Arrays start at 0 but count and per block start at 1. Calculate once.
		$start = ( 0 == $index % 4 );	// Calculate if we're at the start
		$end   = ( $nice_index == $per_block || $nice_index == $total_items );	// Check if we've hit the end
		
		// Display Opening Tag
		if( $start ) {
			print( '<div class="col-md-3">' );	
		}

			// Display image by ID
			wp_get_attachment_image( $image_id, 'full' );
		
		// Display Closing Tag
		if( $end ) {
			print( '</div>' );
		}
		
	} // END Foreach
	
} // END Conditional
