Yes, it is possible. You just have to be patient with it. Many people choose watercolor thinking it’ll be faster and easier to use than other mediums, which isn’t always the case. When going for a realistic style you need to have more of a plan than just seeing what the paint does. You also need to work in many layers and allow for those layers to dry in between. Working from light to dark will also help you not go too dark in the beginning and then not be able to get the contrast you need. Color isn’t as important as an accurate drawing, light, and contrast. The color can be slightly off and still work as long as you have all those other elements.
It takes practice to achieve this style, so you may want to practice on small pieces first before moving on to larger compositions. Happy painting!
