Alright, so I've heard plenty of people cry "NEVER USE A MOUSE FOR ART! ALWAYS USE A TABLET!" I've never had the opportunity to try a real pro tablet, but all of the minor tablets I've tried (recently the Whack 'Em Bamboo) have struck me as much much worse than using the mouse. I've used the mouse to draw for many years. I'm used to it and I have techniques to get the most out of it, so I can't help but wonder if all the blablablah comes down to just doing what you're used to.
So here's me trying to ink this portrait with the tablet and the mouse. Since I'm not used to the tablet (Bamboo), I gave it two tries to even the odds. No undoing. For what it's worth, the mouse image was easier and finished faster, not that I timed it, but it felt like about 75% of the time to complete.
