Another quick post on animating my sketches - I recently found the app, Muglife, that creates 3-D animations of photographs to create memes, etc. Since the app was free, I decided to give it a try on some recent portrait sketches. Amazingly, it recognized my sketches as actual human faces and performed its magic!
For all of these portraits, I just uploaded the photo and let MugLife do its standard magic. I have since paid an additional $3.99 to use the Creative Mode in the app through which you can change the animations to do different things. But, I haven't really used that yet - other than playing around with it.
Have you tried MugLife or other similar apps? I'd love to hear your thoughts and experience with it/them.
