Flexbox center and bottom right item

Is this what you are looking for? http://jsfiddle.net/DIRTY_SMITH/q12bh4se/6/

body {
  background-color: lightblue;
}

#main {
  width: 100%;
  height: 400px;
  border: 1px solid black;
  display: -webkit-flex;
  /* Safari */
  -webkit-align-items: flex-start;
  /* Safari 7.0+ */
  display: flex;
  align-items: flex-start;
}

#main div {
  -webkit-flex: 1;
  /* Safari 6.1+ */
  flex: 1;
}

.flex-item-center {
  margin-left: 40%;
  border-style: solid;
  -webkit-align-self: center;
  /* Safari 7.0+ */
  align-self: center;
}

.flex-item-bottom {
  border-style: solid;
  align-self: flex-end;
}

I've made a posible solution.

.flex-center {
  background-color: #739FD0;
  color: #000000;
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
  justify-content: center;
  align-content: center;
  align-items: center;
  height: 400px;
}
.flex-center-bottom {
  background-color: #739FD0;
  color: #000000;
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
  justify-content: flex-end;
  align-content: center;
  align-items: center;
}
.flex-item-center {
  border: solid 2px #4675AA;
  order: 0;
  flex: 0 1 auto;
  align-self: center;
}
.flex-item-bottom {
  border: solid 2px #4675AA;
  order: 1;
  flex: 0 1 auto;
  align-self: flex-end;
}
<div class="flex-center">
  <div class="flex-item-center">
    <p>DROP FILES HERE</p>
  </div>
</div>
<div class="flex-center-bottom">
  <div class="flex-item-center">
    <p>Hint: You can also drop files in the all files page</p>
  </div>
</div>

}
<div class="flex-center">
