I uploaded a new instructional video on Youtube to demonstrate how to use my "Painter's Guide" app. Please go to: https://www.youtube.com/watch?v=SYWzG4JLpSU to watch it (for Instagram users, please search "Qiang Huang app" on Youtube). I hope all of you can benefit from this free tool to improve your painting quality. Having been teaching for so many year, I feel I have a mission to accomplish: I want to boost up the general capability of representation art creation. I will try all the ways to achieve this goal. Creating apps is one of them. Youtube will soon be another one. At this moment, I have very few videos on Youtube and only 55 people have subscribed my channel. From now on I will use this tool proactively to provide my painting tips and other educational information. I sincerely hope you can support my effort. Please please subscribe my channel. I am serious about art and teaching, and know well that there is too much junk in the world now. I will and am obligated to keep my channel clean. Let's work together, to survive, to grow, to excel, and eventually to make this world more beautiful. Thank you so much.
