It's still all derivative.
You're attempting to mimic popular cartoon styles with absolutely _no_ grasp of the underlying fundamentals. You clearly have not taken any time to learn perspective, proportions or anatomy. You've attempted to jump ahead to the end product and as a result can only produce poorly drawn replications.
Considering said replicas are shaky line notebook doodles, I'm not certain you even grasp aesthetic value. Most people would have--at the very least--cleaned these up and taken the time to scan the images instead of passing off cam shots. That would make it passable for Deviantart standards.
This will hopefully show you that even when producing cartoon characters, an artist still has more going on than you may immediately understand. If you have a sincere desire to ever "improve your art" I suggest you stop trying to take shortcuts and begin by learning basic drawing skills.
