I just love pastels
While pastels are not my favorite medium to draw with, they are quite fun to use. If you're not one for getting your hands messy then I would definantly not recommend them for you. My favorite thing about pastels are the vibrant colors. If you can work the shadows just right you can really make them pop something awesome. They are also good for drawing flowers.
