My first attempt at blending sketch tools on the iPad2. ArtRage is an awesome tool, just cranked out this sketch of a character, based on you know who (you know who you are mwahaha).
A little later I used an app called Rays, to add this effect, though really I could have done this in photoshop.
Another muck around sketch of a mushroom, specifically a Fly Agaric. With one of those item boxes from the super mario series. Glowing in a wave of yellow mushroom glory!
anything that makes you grow must be a good thing. Even if it looks despicably inedible.
