I decided to give the tutorial a try even though I didn't have the right brushes, the right paper or the right pigments, lol. I tend to take that kind of thing as a challenge, and the whole point of a free tutorial is to see if you like the style enough to invest in further classes and/or the correct materials.
Alas. Half way through the tutorial the videos stopped working. I believe that is a problem on my end because I've had wi-fi problems lately. I felt I had seen enough to finish on my own, though.
I do find Anna's style interesting, and the brushes and a few new colors are on my wish list. I won't buy them though until I've fixed my wi-fi problem.
