These days I make it a point to sketch regularly in real media with my tried-and-true collection of drawing tools. I've become something of a collector of pens, paints, and pastels, as I've discovered that changing up your tools forces one to become more adventurous with their techniques. There is also something very satisfying about "conquering" a particular medium or style or technique after you spent so much time wrestling with - wasting precious and expensive materials in the process... I'll never tire of a good challenge!
