I like it. Let's see the whole thing!
Also, I was like you once - I had no idea where to start to draw digitally. If you're willing to spend money, buy a tablet and stylus (they go together most of the time). It will make your life million-folds easier. Wacom usually supplies the tablet and stylus with one or two art softwares, such as ArtRage or Sketchbook Express, for free.
If you decide to go with that route (assuming you do get used to drawing digitally hehe), my number one tip is to WATCH VIDEOS. You probably will not find a digital art tutor, so your best bet to is learn through videos. I watched so many videos that it practically took up the time that I could've done just drawing, however, I guarantee you it will be worth it. You'll also acquire a better understanding of "organization" as well as other skills I guess. Layers, masks, and all that.
A good website that I can link you to is https://cgcookie.com/concept/cgc-courses/getting-started-in-digital-art/
It teaches you all the basics in eight 7-10 minute videos.
