I see how you like drawing and art. However, I think you need to work more on the anatomy to then break the rules. Try to use references and apps for them. You can also work a bit more on the shading to see where the light is coming from (if it's coming from the front, back or side) and make sure it's suggested, not necessarily visible. Try to study some drawing methods such as the Loomis one to then work on your more cartoonlike art style.
