Zelda is one of the most motivated and down to earth artists I know. I first "discovered" her when she was working more as a part of "Teetering Bulb", but now she's gone solo.
Like me, she's a huge believer in the 10,000 hours to mastery theory. It's not about "talent", it's about having faith in yourself and the discipline to put in the focused hours. I can certainly see that her results speak for themselves.
