They're ok. I think, aside from practice, if you really want to get better you should actively seek out information on how to draw. Nobody likes hearing that, and I'm not saying you can't draw. I am
saying human civilization is built upon the knowledge of those who came before us. As such, there's a wealth of information on drawing that we can use to get better.
Check out 'The New Drawing on the Right Side of the Brain' by Betty Edwards. It's a book on drawing from observation and realism. Even if you have no interest in either of those things, knowing how to do both will help you. Necessary? Perhaps not, but if you want to improve in all areas of your drawing ability it's certainly not a bad idea.
Not to mention it's actually a fairly interesting read, also dealing with how we perceive the world around us and how our brain interprets (sometimes to our disadvantage) the information it receives.
if you want to hit me up up on DA.
