Best of luck to you. If I can add some advice, and just take it as some advice. Never neglect what you would think as the boring stuff, like drawing tables. Backgrounds are important, and making the characters look as if they move is also important. Perspective is also a key ingredient in art too. You aren't telling the situation, you are showing it. Also make sure you can draw every day, any spare moment your have, even if you aren't inspired. Reading good manga is also helpful, but also find and develop your own style of art/storytelling.
