Believe it or not having less options as an artist sometimes brings out all sorts of hidden talents lol. In Facebook for example some of the art is amazing, the artists would be using either a mouse or some sort of drawing tablet, and if anyones tried to use a mouse in paint to draw, you understand the limits, but there are obviously some patient, talented people out there.
I thought I'd give you a look at some pieces from the Facebook application, Graffiti.
Even my children are giving it a go.
These are some I've done, not as good as some, but good for me, especially since I can't draw this good with a pencil. But the app is very forgiving, if somewhat frustrating at times, but go and give it a go. It is a bit addicting though, just warning you now.
