Graphite: 3H, 2H, H, 4B on paper, 5.5x8.5 inches. Just a simple practice on drawing hand positions, not meant to be perfectly blended, but more a focus of form and shapes based on the lines and curves.
...ok...good job on the palms and the wrists? Some tips: Your fingers should be wider, and don't bend them all the same direction when doing one like the bottom sketch. When the hand is relaxed the outside fingers always bend inwards. Good job though on the upper hand, it looks very natural, and I like your style on it. Did you use any reference for these? Your best friends when drawing hands are your own, and you can find a lot of good, though maybe stylized references here on the site. These aren't bad, keep up the practice though, hands and feet are tough to draw.
