Hi Vanillabook,
i like your gesture drawings. Especially, because they are your first try. I would advise you not to do 30 second drawings. Especially when beginning, you need some time to grasp proportion and anatomy. 60 seconds is minimum ( and still very short). Dont worry too much about correct anatomy. this will come with time. i advise you to draw the bigger parts of the body: torso, legs, arms, head. Dont focus on eyes, ears , fingers and tooth too much. This will distract you from what is important.
The most important thing is to start and than, to continue. You wont believe, how much you will improve in no time.
Keep it up!
