welcome to 2draw!! this is really good for your first picture on this site. I still see a couple things that could improve though. you might want to color in those little white spots all over the pic. I hear they are called "fill noise". meh.
Welcome to 2draw. The colored lineart is a nice start, and the colors work well together, but you don't have enough command of your lineart or shading for intermediate yet. In the future, try using different thicknesses of line, and layers. Additionally, 14-minute pictures almost never stay on the intermediate board. You will need to practice significantly before being able to post there.
