First: Thank you so much, I'm glad you like them! Second: Hmm, if you really want to draw, the most important thing is that you have to draw every single say. It doesn't matter if you draw 16 hours or just ten minutes, as long as drawing is a part of your life and you have fun with learning, you'll improve. Of course, improvement is faster if you practice more, but after a while you'll be watching your surroundings more carefully. Like if you have trouble with hands, you'll find yourself watching your hand more often, etc. If you think drawing is fun, then draw, it doesn't have to take up too much time and it can be really relaxing, especially if you're busy!
