Word image manipulation

So i have continued using Microsoft Word to digitally manipulate images as you can see below:
As you've probably noticed i've printed and re-scanned them in - i like the faded quality, and i havent yet been able to save the images i create on Word in high quality formats. They're usually very small.

Over the next few days im hoping to address issues such as the flatness of the images, i would like an extra layer of depth and will do so using my scanner
