Thankfully I have a Pentel Brush pen and I've used it before BUT I've mainly used it in botanical/floral art. I wanted to try something a little different, something away from my comfort spot so to speak. I thought this particular mushroom would give me a chance to put several of the concepts covered in the class to use. Varying line weight, speed and even a little abstract drawing (which I'm really uncomfortable with-lol). I did do a quick sketch in pencil of the basic outline and key 'landmark' points but that's all. I went all out and just drew by the seat of my pants! LOL Which again is not usual or comfortable for me. I'm glad I took the class!
