I can't stop drawing sketch cards!
Who wants to join me in this addiction? They can be cards of anything. But, for whatever reason, drawing sketch cards is addictive. It might be due to the small size I'm working in (trading card size), and working small allows me to draw in larger quantities. Whatever the reason, I can't stop drawing them and I keep adding more and more characters to my list of people to draw!
My brother and I are artists. And he actually created dozens of Sonic trading cards a few years ago. He even added "lost" Sonic characters like Bean, Bark, Fang, Heavy & Bomb (etc). It was really fun, to the point where my sister and her husband came over from their apartment to play the card game with us. I don't know where they are now, but he was very thorough and detailed with creating the rules of the fighting game.
I tried my hand at creating some myself, but I wasn't nearly as creative with making them as he was. Nowadays he doesn't even draw anymore for whatever reason.
