CSS Mask-image won't work - html

Question

I am trying to mask image (with text shadow) using CSS property -webkit-mask-image.
I understand that I can use background-clip however I need to do this using only mask-image
property for some reason. However upon trying it out I was stack with some CSS codes.
here's my CSS code:
#masking h1, span.mask-text {
font-size: 230px;
font-family: 'Lilita One', sans-serif;
text-align: center;
margin: 0 auto;
padding: 0;
-webkit-text-fill-color:transparent;
position:absolute;
left: 100px;
}
#masking h1 {
text-shadow: 3px 3px 0px #34495e;
z-index:2;
}
span.mask-text {
-webkit-mask-image: url('http://halloweenmaternitycostumes.com/wp-content/uploads/2014/11/paper.jpg') no-repeat center center;
background-size: cover;
z-index:5;
-webkit-transition:all 0.7s ease;
-moz-transition:all 0.7s ease;
-o-transition:all 0.7s ease;
transition:all 0.7s ease;
}
span.mask-text:hover{
cursor: pointer;
-webkit-mask-image: ('http://halloweenmaternitycostumes.com/wp-content/uploads/2014/11/paper-hover.jpg') no-repeat center center;
background-size: cover;
z-index:5;
}
span.mask-text:after {
content: 'Mask Text';
text-transform: uppercase;
}
Here's an image what I am trying to do:

I updated your code here:

To add a background to the text, do as follows... Note: background must come before clipping!
span{
font-size: 50px;
font-family: Helvetica, Arial;
background: url(http://www-users.cs.umn.edu/~interran/texture/lic2.gif);
-webkit-background-clip: text;
-webkit-text-fill-color: transparent;
}
<span>Text</span>
Your code does two things novel-- animation and text-shadow. For the text-shadow, I made sure that your span and h1 both had font-weight:bold (by default, one is bold and the other is not). For the animation, I left it up to you to customize. You'll need to change the easing and background position.
