Seriously, how did you do that marvelous shading? I use a simple stylus from Michael's and still haven't managed to get shading like that. Mine always ends up splotchy. Do you have one of those fancy styluses that are attached to a device with a knob that can change temperatures by small degrees?
Hi! I don't change the temperature. I get smooth shadows by changing the driving speed of the pen on the surface. The faster i drive the pen, the lighter shade. Sometimes i blow on the pen, thereby regulating heating. That's the whole my secret.
