I'm very lucky to have almost everyone in my family be absolutely amazing at art (haha) but I believe that art is completely practice and how you view things. As others have said, a little praise goes a long way. My old art teacher at the local boys and girls club used to always absolutely love my work. (or pretend ;D) but either way, it helps a ton. Just practice, practice, practice. If you want to learn the basics, learn bone structures and basic anatomy. I would suggest buying an actual book, because in my opinion it's way better than looking at a computer screen D: Good luck :]
