That was fun to make this project with Di Ujdi. In her course, I was able to get a lot of valuable information about sketch for illustration and composition. Many thanks for the suggestions on how to use the Color Guide in the Adobe Illustrator. I have always had difficulty choosing the right colours. It helped me a lot in my project, which I created after the course. I think that it worked out well. I am so happy to get these skills.
My illustration from sketch to the artwork is here.
