Oh, this warms my heart. I love to see starting artists.
To begin, there are several skills associated with drawing/art, but the most important one to a beginner artist is anatomy. Due to a cruel reality, this is also the most difficult one to master.
I would suggest going to
this site and using their practice tool. You're also interested in chibis, which are also good for a starting artist, as they're fairly simple and will help you in learning to draw basic shapes. Just find (preferably, rather simple, as they are the most easy to copy) chibis online and copy them as closely as you can. As your skill improves, you will be able to draw without a guide.
And... This is
technically cheating, but another resource for drawing realistic bodies is
here. Just slam in how tall your drawing will be and it will tell you where to put the body parts. For a beginner, it's great for getting a sense of the proportions of the body. Once you get a sense for them, though, I would suggest not using it anymore as it can easily become a crutch.
I think the last piece of advice I can give you is don't give up. Learning how to draw can be very frustrating, and it's still very frustrating even to artists whose work seems flawless. Just keep in mind that, when you get frustrated, it's just a sign that your skill to see the errors in art is improving.
Hope this helped.
