Having a smartphone now can really ease up submission. Perviously, submitting an art (traditional) can be a hassle if you don't have a scanner. And you must use a computer. Though I used smartphone to upload before but the web interface is hard to operate when you are using phones.
Until I saw deviant art app. Sceptical but decide to give it a try and yes it sure helps a lot. And joining a doddle group in Facebook made me doodle almost daily. I'd try to upload as much as possible. After all, doodling is fun!
