Your first experience of painting a plastic tub and the whole process behind it is quite wonderful. For those who are used to sketching with graphite pencils, suddenly working with brushes and acrylic colors is like a big change. I like your color selection. Bright colors like crepe, pink and orange usually suit clay or plastic tubs well. Although at first it seems like just a few simple strokes of horizontal and diagonal lines, when the spaces are finally filled with orange color, the whole design takes on a geometric and vibrant form. The stake or groove pattern that you have created on the pink line with crepe at the very beginning is the main attraction of the entire work. As a first work experience, the finishing of the lines and the color combination are quite clean. I think its beauty will be doubled when a small green tree or indoor plant is planted in this colorful tub. It's really great to see such a colorful and creative work for the first time. Best of luck to you in this contest. 😊
