It's really not that bad. The designs are imaginative and interesting. The lineart is wobbly, and the forms are not anatomically accurate visually. The style look intentionally messy. But it doesn't work well in my opinion. The way the forms attach seem unnatural. like they are flattened and have no volume to them. Try constructing your pieces with more basic shapes.
The rat shines in this style because it gets to be pushed and have character to it. That's the best part of this image.
