Hi janoot. Those look pretty good. Your lines are neat and you did good job capturing proportions. About pictures I would guess that it was either not enough light in the room where you were taking them, or you draw with very little pressure, so that the lines are not very visible. I would try to make more confident strokes with pressing the pencil more against the paper. Try maybe before each drawing session to do some warmups and fill couple of pages with just random lines elipses and curves and test how hard you can go, so that it'll be easier when you draw. To avoid smudging I always place empty piece of paper on the area I already shaded, so that my hand is resting on that instead of the drawing. Good job, and keep posting!
