doesn't surprise me that twitter went into a crazy fight over nothing -_-, I would say that digital programs are like a brush or a colour, a tool that you can use, it's a great and awesome tool but a tool none the less, though it shouldn't be your only tool, better to have more then one string on your bow don't you think?, but saying that it shouldn't be used is really dumb =/
like saying I can't use a marker or a brush for a painting instead I should use a crayon or my hands dumb
@lunaartemisasama
make random patterns(like a round spiky ball) and play with texturing and others effects (I use Photoshop mostly and create my own brushes), natural is mostly the absence of textures and imperfections in the brushes since in real life brushes and any other painting tool leaves a texture/imperfections behind, be it the paper or the grooves in the paint, so try emulating those imperfections and textures and your good to go (hope it helps =) )

is the dress blue or white? XD the world hangs in the balance by this question
