Some advice:
1) Don't worry about titles for your drawings.
2) Do life drawing. Do a LOT of life drawing. Drawing from your imagination or a picture is okay, but if you want to improve you need to sit down in front of something and draw it. People, places, objects... still lifes will help you with your form, texture, and rendering technique, and drawing models or people around you (especiall if it's transient, because then you have to draw quickly) will help develop your muscle memory as well as give you a better understanding of the theory of how people are put together. In other words, anatomy.
Oh, and get an art student's anatomy book. They help a ton.
Keep drawing! Fill several pages of a sketchbook a day with life drawings if you can.
