I always like to draw self-potrait, but it's a time when I was boring with single picture, and want to make it more connect, multidimensional, so I though about gif.
At first, I used Fast Burst Camera to take photos of myself moving my head, about 20 frames. Then I did a quick sketch of each frame by yellow crayon, scaned and used Photoshop to crop it in right positions. The result is a sketch animation.
After that, I used black fountain pen to draw over yellow crayon lines, Scaned again and made the final animation.
It took me a sunday to do that project, in the end I really liked the sketch gif more than the final gif, and its good to realized that.
