I have noticed a few of my friends on facebook are doing the 'sketch your photo'. I tried it on my own and found it extremely amazing. Like one of the user commented ' how can he stop?'
Here are some of the sketches that I have developed via 'SKETCH YOUR PHOTO' on facebook.
There are several templates for you to choose even some with the 'Halloween' theme. You just need to upload your selected photos and get the effects as above. Do try it yourself.
