At first glance, the class didn't appear too difficult. However, I found conveying the clarity and vividness of color mixing to be the most challenging aspect. In my opinion, I haven't fully mastered it yet, as I had to paint most parts of the rose in 2-3 layers to achieve the desired colors. Nonetheless, I genuinely enjoyed the class, and I appreciate the effort you put into preparing it! Hopefully, I'll have the opportunity to paint more yellow flowers in the future. Thank you, Chris!
