Hmm… well what I can see… is that you mostly draw stuck figures… so maybe just try making… shapes… draw shapes… that will help. Why you may be wondering? In order to draw more complex art you must be able to draw shapes well. For example, a character. Most artist use an outline before they make a character. It’s like a skeleton. It helps with proportions and posing and helps make a whole character. It’s the first thing I want you to practice.
