Hello Sarosna! I mostly like all of your drawings, yes i can see you sometimes lose yourself a bit on the details, you may even try and do 30 sec drawings, just a sheet full of them. That way you will be forced to avoid the little details, and get even more motion. Another thing, you wont also have time to take that much strokes when drawing the shape of the dog, you may want to try to shape it with only 1 or 2 strokes, so you have time to get a more complete drawing of the animal and get more motion in to it.
Keep it up! : )
