I approached it a different way although this may require you to edit the height and width of your image a little.

First I removed the image from that Div and added a class bg-smile

<div class="col-sm bg-smile">
  <!-- stays empty -->
</div>

I've also added mb-0 to remove the bottom margin from the 3rd text box so the image exactly lines up at the bottom.

Then added a few CSS instructions for the new class and to make the smile image a background of the Div and center it.

.bg-smile{
  background: url(https://www.codeply.com/images/partner_creativetim.png) 50% 50% no-repeat;
}
