Hand Drawn Picture Style in Gimp

So I stumbled across this cool way to style pictures after trying to make it look like a sketch on gimp. This instructable is an explanatory one about how you could also make this nice looking piece of art for your own with most if not all pictures. BTW, the first picture is me, the second picture is my sister, and the third is my parents. So you could go to the next step now if you want. Go now! Shoo!

These are what you will need:
-Gimp
-a computer
-some hands
-a brain
-a picture
-something to make the picture with
-time
-the ability to move on to the next step

Select your picture...

If you want you can experiment with values and stuff to make it look different or change colors or color it in or something. I hope that you enjoyed it and that you can show us the art that you did. Arrivederci.
