How to align a background image with padding?

Question

I have a <div> with a left aligned background image and some text.

I need the div (or an inner div) to have some padding so the text will start next to background image, not on it. Is there a way to do this with CSS?

Here is a fiddle and the CSS:

.mydiv {
  background-image: url('http://vignette3.wikia.nocookie.net/starwars/images/d/d6/Human_NEGAS.jpg/revision/latest?cb=20090709062312');
  background-position: left bottom;
  background-size: contain;
  background-repeat: no-repeat;
  background-color: #fff;
  width: 500px;
  height: 700px;
}

Flexbox and a pseudo-element could do this...assuming I have your intention right.

I need the div (or inner div) has some padding so the text will start next to background image, not on it

Basically, the inner div is 100% height of the parent element but any space after the text is taken up by the pseudo-element which has the image as a background.

* {
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  padding: 0;
  margin: 0;
}
.mydiv {
  background-repeat: no-repeat;
  background-color: white;
  width: 100vw;
  height: 100vh;
}
.mydiv div {
  display: flex;
  height: 100%;
}
.mydiv div:after {
  content: '';
  background-image: url('http://vignette3.wikia.nocookie.net/starwars/images/d/d6/Human_NEGAS.jpg/revision/latest?cb=20090709062312');
  background-position: left bottom;
  background-size: contain;
  background-repeat: no-repeat;
  flex: 1;
}

<div class="mydiv">
  <div>My Text here</div>
</div>

REVISION/ALTERNATE after commented requirements updated

I want the text starting next to image (on the right side of the background image), not on the image. The reason I want the image background because I want it to be a fixed background located bottom-left corner. I want the background image contained because I want the width of the image automatically calculated.

You would need to change the structure and put the image inline

* {
  margin: 0;
  padding: 0;
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
}
.mydiv {
  width: 100vw;
  height: 100vh;
  display: flex;
}
.imgdiv {
  height: 100%;
}
.imgdiv img {
  max-height: 100vh;
  max-width: 100%;
}
.textdiv {
  flex: 1 0 auto;
}

<div class="mydiv">
  <div class="imgdiv">
    <img src="http://vignette3.wikia.nocookie.net/starwars/images/d/d6/Human_NEGAS.jpg/revision/latest?cb=20090709062312" alt="">
  </div>
  <div class="textdiv">My Text here</div>
</div>
