但是，我希望将红色轮廓替换为图像，例如：

我尝试了 :before 和 :after 伪标签，但没有找到解决方案。我应该朝着哪个方向来实现这一目标？

你可以像这样使用多个背景：

.box {
 width:200px;
 height:210px;
 border-radius: 0 0 50% 50%/0 0 70% 70%;
 background:
  url(https://i.stack.imgur.com/bdZeE.png) center/cover, 
  url(https://i.stack.imgur.com/i7iHM.png) 0 180%/100% auto no-repeat;
 position:relative;
}
.box:after {
  content:"";
  position:absolute;
  z-index:1;
  bottom:0;
  top:50%;
  left:0;
  right:0;
  background:url(https://i.stack.imgur.com/i7iHM.png) 0 90%/100% auto no-repeat;
}

<div class="box">

</div>

你也可以使用 CSS 变量控制里面的图片：

.box {
 width:200px;
 height:210px;
 border-radius: 0 0 50% 50%/0 0 70% 70%;
 background:
  var(--image) center/cover, 
  url(https://i.stack.imgur.com/i7iHM.png) 0 180%/100% auto no-repeat;
 position:relative;
 display:inline-block;
}
.box:after {
  content:"";
  position:absolute;
  z-index:1;
  bottom:0;
  top:50%;
  left:0;
  right:0;
  background:url(https://i.stack.imgur.com/i7iHM.png) 0 90%/100% auto no-repeat;
}

<div class="box" style="--image:url(https://i.stack.imgur.com/bdZeE.png)">
</div>
<div class="box" style="--image:url(https://i.stack.imgur.com/7A8fP.png)">
</div>
