Incredible gouache painting tutorial—looks like oils or airbrush

I don't know why videos show up so small in here, and in a square format with black bars top and bottom. That does not look good, and there doesn't seem to be a way to change it. But this is the best gouache painting tutorial I've ever seen. I got all excited about the airtight palette, found one on Amazon, but then remembered my past experiences trying that with Alkyd paints. Not good—they just dry out. I found a comment where somebody asked her about it, and she said hers tend to dry out too, and I assume she uses it just about every day. 

But I think (one) reason her approach is working so much better than mine is because she has all those well-mixed colors at hand—that's what I call a candy box. I mix mine on a butcher's tray and usually don't make enough colors or close-enough blends. I think I'm afraid of wasting too much paint. 

Another factor is she uses washes a lot more than I've seen before. Plus so many tricks—the ultra-fine miniature brushes, drybrushing etc. She was making a very detailed painting, whereas for the Watts method they're doing sketches. 

She said she's had talent from an early age and just studied every book she could find on art technique. I suspect it's a case of extreme patience and discipline, much like it seems to be for Kim Jung Gi. I watched a bunch of videos about him last night. Inspiration overdose.
